Incorrect membership handling of group sharing feature

Aki Tuomi reports:

lib-smtp doesn't handle truncated command parameters properly, resulting in infinite loop taking 100% CPU for the process. This happens for LMTP (where it doesn't matter so much) and also for submission-login where unauthenticated users can trigger it.

Aki also reports:

Snippet generation crashes if: message is large enough that message-parser returns multiple body blocks The first block(s) don't contain the full snippet (e.g. full of whitespace) input ends with '>'

Reno Robert reports:

FreeBSD uses a two-process model for running a VM. For booting non-FreeBSD guests, a modified grub-emu is used (grub-bhyve). Grub-bhyve executes command from guest grub.cfg file. This is a security problem because grub was never written to handle inputs from OS as untrusted. In the current design, grub and guest OS works across trust boundaries. This exposes a grub to untrusted inputs from guest.

grub-bhyve (emu) is built without SDL graphics support which reduces lot of gfx attack surface, however font loading code is still accessible. Guest can provide arbitrary font file, which is parsed by grub-bhyve running as root.

In grub-core/font/font.c, read_section_as_string() allocates section->length + 1 bytes of memory. However, untrusted section->length is an unsigned 32-bit number, and the result can overflow to malloc(0). This can result in a controlled buffer overflow via the 'loadfont' command in a guest VM grub2.cfg, eventually leading to privilege escalation from guest to host.

Reno Robert also reports:

GRUB supports commands to read and write addresses of choice. In grub-bhyve, these commands provide a way to write to arbitrary virtual addresses within the grub-bhyve process. This is another way for a guest grub2.cfg, run by the host, to eventually escalate privileges.

These vulnerabilities are mitigated by disabling the 'loadfont', 'write_dword', 'read_dword', 'inl', 'outl', and other width variants of the same functionality in grub2-bhyve.

There is also work in progress to sandbox the grub-bhyve utility such that an escaped guest ends up with nobody:nobody in a Capsium sandbox. It is not included in 0.40_8.

Mitre reports:

In libexif, there is a possible out of bounds write due to an integer overflow. This could lead to remote escalation of privilege in the media content provider with no additional execution privileges needed. User interaction is needed for exploitation.

Adobe reports:

• This update resolves a type confusion vulnerability that could lead to arbitrary code execution (CVE-2020-3757).

NGINX Team reports:

NGINX before 1.17.7, with certain error_page configurations, allows HTTP request smuggling, as demonstrated by the ability of an attacker to read unauthorized web pages in environments where NGINX is being fronted by a load balancer.

Upstream ksh93 maintainer Siteshwar Vashisht reports:

A flaw was found in the way ksh evaluates certain environment variables. An attacker could use this flaw to override or bypass environment restrictions to execute shell commands. Services and applications that allow remote unauthenticated attackers to provide one of those environment variables could allow them to exploit this issue remotely.

Micah Snyder reports:

A denial-of-service (DoS) condition may occur when using the optional credit card data-loss-prevention (DLP) feature. Improper bounds checking of an unsigned variable resulted in an out-of-bounds read, which causes a crash.

MITRE CVE reports:

Django 1.11 before 1.11.28, 2.2 before 2.2.10, and 3.0 before 3.0.3 allows SQL Injection if untrusted data is used as a StringAgg delimiter (e.g., in Django applications that offer downloads of data as a series of rows with a user-specified column delimiter). By passing a suitably crafted delimiter to a contrib.postgres.aggregates.StringAgg instance, it was possible to break escaping and inject malicious SQL.

The libssh team reports:

In an environment where a user is only allowed to copy files and not to execute applications, it would be possible to pass a location which contains commands to be executed in additon.

When the libssh SCP client connects to a server, the scp command, which includes a user-provided path, is executed on the server-side. In case the library is used in a way where users can influence the third parameter of ssh_scp_new(), it would become possible for an attacker to inject arbitrary commands, leading to a compromise of the remote target.

Oracle reports:

This Critical Patch Update contains 17 new security fixes for Oracle MySQL. 5 of these vulnerabilities may be remotely exploitable without authentication, i.e., may be exploited over a network without requiring user credentials.

The Apache SpamAssassin project reports:

A nefarious rule configuration (.cf) files can be configured to run system commands. This issue is less stealthy and attempts to exploit the issue will throw warnings.

Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.

Todd C. Miller reports:

Sudo's pwfeedback option can be used to provide visual feedback when the user is inputting their password. For each key press, an asterisk is printed. This option was added in response to user confusion over how the standard Password: prompt disables the echoing of key presses. While pwfeedback is not enabled by default in the upstream version of sudo, some systems, such as Linux Mint and Elementary OS, do enable it in their default sudoers files.

Due to a bug, when the pwfeedback option is enabled in the sudoers file, a user may be able to trigger a stack-based buffer overflow. This bug can be triggered even by users not listed in the sudoers file. There is no impact unless pwfeedback has been enabled.

the Apache Spamassassin project reports:

nefarious rule configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. This issue is less stealthy and attempts to exploit the issue will throw warnings.

OpenSMTPD developers report:

An incorrect check allows an attacker to trick mbox delivery into executing arbitrary commands as root and lmtp delivery into executing arbitrary commands as an unprivileged user

Problem Description:

A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers.

Impact:

An attacker in control of the URL to be fetched (possibly via HTTP redirect) may cause a heap buffer overflow, resulting in program misbehavior or malicious code execution.

A programming error allows an attacker who can specify a URL with a username and/or password components to overflow libfetch(3) buffers.

Problem Description:

A missing check means that an attacker can reinject an old packet and it will be accepted and processed by the IPsec endpoint.

Impact:

The impact depends on the higher-level protocols in use over IPsec. For example, an attacker who can capture and inject packets could cause an action that was intentionally performed once to be repeated.

Problem Description:

Due to incorrect initialization of a stack data structure, up to 20 bytes of kernel data stored previously stored on the stack will be exposed to a crashing user process.

Impact:

Sensitive kernel data may be disclosed.

Pillow developers report:

This release addresses several security problems, as well as addressing CVE-2019-19911.

CVE-2019-19911 is regarding FPX images. If an image reports that it has a large number of bands, a large amount of resources will be used when trying to process the image. This is fixed by limiting the number of bands to those usable by Pillow.

Buffer overruns were found when processing an SGI, PCX or FLI image. Checks have been added to prevent this.

Overflow checks have been added when calculating the size of a memory block to be reallocated in the processing of a TIFF image.

The Gitea Team reports:

• Hide credentials when submitting migration

• Prevent redirect to Host
• Hide public repos owned by private orgs

Intel reports:

.A potential security vulnerability in Intel(R) Processor Graphics may allow information disclosure. Intel is releasing software updates to mitigate this potential vulnerability.

Description: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may allow an unauthenticated user to potentially enable information disclosure via local access.

This patch provides mitigation for Gen9 hardware only. Patches for Gen7 and Gen7.5 will be provided later. Note that Gen8 is not impacted due to a previously implemented workaround. The mitigation involves using an existing hardware feature to forcibly clear down all EU state at each context switch.

Art Manion and Will Dormann report:

By using an older and less-secure form of open(), it is possible for untrusted template files to cause reads/writes outside of the template directories. This vulnerability is a component of the recent Citrix exploit.

National Vulnerability Database:

There's a possible information leak / session hijack vulnerability in Rack (RubyGem rack). This vulnerability is patched in versions 1.6.12 and 2.0.8. Attackers may be able to find and hijack sessions by using timing attacks targeting the session id. Session ids are usually stored and indexed in a database that uses some kind of scheme for speeding up lookups of that session id. By carefully measuring the amount of time it takes to look up a session, an attacker may be able to find a valid session id and hijack the session. The session id itself may be generated randomly, but the way the session is indexed by the backing store does not use a secure comparison.

Cary Phillips reports:

OpenEXR (IlmBase) v2.4.0 fixes the following security vulnerabilities:

• CVE-2018-18444 Issue #351 Out of Memory
• CVE-2018-18443 Issue #350 heap-buffer-overflow

The relevant patches have been backported to the FreeBSD ports.

wordpress developers reports:

Four security issues affect WordPress versions 5.3 and earlier; version 5.3.1 fixes them, so youll want to upgrade. If you havent yet updated to 5.3, there are also updated versions of 5.2 and earlier that fix the security issues. -Props to Daniel Bachhuber for finding an issue where an unprivileged user could make a post sticky via the REST API. -Props to Simon Scannell of RIPS Technologies for finding and disclosing an issue where cross-site scripting (XSS) could be stored in well-crafted links. -Props to the WordPress.org Security Team for hardening wp_kses_bad_protocol() to ensure that it is aware of the named colon attribute. -Props to Nguyen The Duc for discovering a stored XSS vulnerability using block editor content.

Typo3 core team reports:

It has been discovered that the output of field validation errors in the Form Framework is vulnerable to cross-site scripting.

It has been discovered that t3:// URL handling and typolink functionality are vulnerable to cross-site scripting. Not only regular backend forms are affected but also frontend extensions which use the rendering with typolink.

It has been discovered that the output table listing in the Files backend module is vulnerable to cross-site scripting when a file extension contains malicious sequences. Access to the file system of the server - either directly or through synchronization - is required to exploit the vulnerability.

It has been discovered that the extraction of manually uploaded ZIP archives in Extension Manager is vulnerable to directory traversal. Admin privileges are required in order to exploit this vulnerability. Since TYPO3 v9 LTS, System Maintainer privileges are required as well.

Failing to properly escape user submitted content, class QueryGenerator is vulnerable to SQL injection. Having system extension ext:lowlevel installed and a valid backend user having administrator privileges are required to exploit this vulnerability.

It has been discovered that classes QueryGenerator and QueryView are vulnerable to insecure deserialization. Requirements for successfully exploiting this vulnerability (one of the following): - having system extension ext:lowlevel (Backend Module: DB Check) installed and valid backend user having administrator privileges - having system extension ext:sys_action installed and valid backend user having limited privileges

TYPO3 allows to upload files either in the backend user interface as well as in custom developed extensions. To reduce the possibility to upload potential malicious code TYPO3 uses the fileDenyPattern to deny e.g. user submitted PHP scripts from being persisted. Besides that it is possible for any editor to upload file assets using the file module (fileadmin) or changing their avatar image shown in the TYPO3 backend. Per default TYPO3 allows to upload and store HTML and SVG files as well using the mentioned functionalities. Custom extension implementations probably would also accept those files when only the fileDenyPattern is evaluated. Since HTML and SVG files - which might contain executable JavaScript code per W3C standard - could be directly displayed in web clients, the whole web application is exposed to be vulnerable concerning Cross-Site Scripting. Currently the following scenarios are known - given an authenticated regular editor is able to upload files using the TYPO3 backend: - directly target a potential victim to a known public resource in a URL, e.g. /fileadmin/malicious.svg or /fileadmin/malicious.html - using the TypoScript content object ?SVG? (implemented in class ScalableVectorGraphicsContentObject) having renderMode set to inline for SVG files (available since TYPO3 v9.0) - custom implementations that directly output and render markup of HTML and SVG files SVG files that are embedded using an img src=?malicious.svg? tag are not vulnerable since potential scripts are not executed in these scenarios (see https://www.w3.org/wiki/SVG_Security). The icon API of TYPO3 is not scope of this announcement since SVG icons need to be registered using an individual implementation, which is not considered as user submitted content.

It has been discovered that request handling in Extbase can be vulnerable to insecure deserialization. User submitted payload has to be signed with a corresponding HMAC-SHA1 using the sensitive TYPO3 encryptionKey as secret - invalid or unsigned payload is not deserialized. However, since sensitive information could have been leaked by accident (e.g. in repositories or in commonly known and unprotected backup files), there is the possibility that attackers know the private encryptionKey and are able to calculate the required HMAC-SHA1 to allow a malicious payload to be deserialized. Requirements for successfully exploiting this vulnerability (all of the following): - rendering at least one Extbase plugin in the frontend - encryptionKey has been leaked (from LocalConfiguration.php or corresponding .env file).

Drupal Security Team reports:

A visit to install.php can cause cached data to become corrupted. This could cause a site to be impaired until caches are rebuilt.

Drupal 8 core's file_save_upload() function does not strip the leading and trailing dot ('.') from filenames, like Drupal 7 did. Users with the ability to upload files with any extension in conjunction with contributed modules may be able to use this to upload system files such as .htaccess in order to bypass protections afforded by Drupal's default .htaccess file. After this fix, file_save_upload() now trims leading and trailing dots from filenames.

The Media Library module has a security vulnerability whereby it doesn't sufficiently restrict access to media items in certain configurations.

The Drupal project uses the third-party library Archive_Tar, which has released a security-related feature that impacts some Drupal configurations. Multiple vulnerabilities are possible if Drupal is configured to allow .tar, .tar.gz, .bz2 or .tlz file uploads and processes them. The latest versions of Drupal update Archive_Tar to 1.4.9 to mitigate the file processing vulnerabilities.

Ted Y. Ts'o reports:

A maliciously corrupted file systems can trigger buffer overruns in the quota code used by e2fsck.

The OpenSSL project reports:

rsaz_512_sqr overflow bug on x86_64 (CVE-2019-1551) (Low)

There is an overflow bug in the x64_64 Montgomery squaring procedure used in exponentiation with 512-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a result of this defect would be very difficult to perform and are not believed likely. Attacks against DH512 are considered just feasible. However, for an attack the target would have to re-use the DH512 private key, which is not recommended anyway. Also applications directly using the low level API BN_mod_exp may be affected if they use BN_FLG_CONSTTIME.

Matrix developers report:

CVE list:

.

GNU libidn2 before 2.2.0 fails to perform the roundtrip checks specified in RFC3490 Section 4.2 when converting A-labels to U-labels. This makes it possible in some circumstances for one domain to impersonate another. By creating a malicious domain that matches a target domain except for the inclusion of certain punycoded Unicode characters (that would be discarded when converted first to a Unicode label and then back to an ASCII label), arbitrary domains can be impersonated.

As part of IPU 2019.2, INTEL-SA-00242 advises that insufficient access control may allow an authenticated user to potentially enable escalation of privilege via local access.

INTEL-SA-00260 advises that insufficient access control may allow an authenticated user to potentially enable denial of service via local access.

Django release reports:

CVE-2019-19118: Privilege escalation in the Django admin.

Since Django 2.1, a Django model admin displaying a parent model with related model inlines, where the user has view-only permissions to a parent model but edit permissions to the inline model, would display a read-only view of the parent model but editable forms for the inline.

Submitting these forms would not allow direct edits to the parent model, but would trigger the parent model's save() method, and cause pre and post-save signal handlers to be invoked. This is a privilege escalation as a user who lacks permission to edit a model should not be able to trigger its save-related signals.

The WebKitGTK project reports multiple vulnerabilities.

NIST reports: (by search in the range 2018/01/01 - 2019/11/10):

urllib3 before version 1.23 does not remove the Authorization HTTP header when following a cross-origin redirect (i.e., a redirect that differs in host, port, or scheme). This can allow for credentials in the Authorization header to be exposed to unintended hosts or transmitted in cleartext.

In the urllib3 library through 1.24.1 for Python, CRLF injection is possible if the attacker controls the request parameter.

The urllib3 library before 1.24.2 for Python mishandles certain cases where the desired set of CA certificates is different from the OS store of CA certificates, which results in SSL connections succeeding in situations where a verification failure is the correct outcome. This is related to use of the ssl_context, ca_certs, or ca_certs_dir argument.

Micah Snyder reports:

A Denial-of-Service (DoS) vulnerability may occur when scanning a specially crafted email file as a result of excessively long scan times. The issue is resolved by implementing several maximums in parsing MIME messages and by optimizing use of memory allocation.

Intel discovered a previously published erratum on some Intel platforms can be exploited by malicious software to potentially cause a denial of service by triggering a machine check that will crash or hang the system.

Malicious guest operating systems may be able to crash the host.

Starting with version 1.26, the devcpu-data port/package includes updates and mitigations for the following technical and security advisories (depending on CPU model).

Please refer to the security advisories listed above for detailed information.

Unbound Security Advisories:

Recent versions of Unbound contain a vulnerability that can cause shell code execution after receiving a specially crafted answer. This issue can only be triggered if unbound was compiled with --enable-ipsecmod support, and ipsecmod is enabled and used in the configuration.

The Asterisk project reports:

A remote authenticated Asterisk Manager Interface (AMI) user without system authorization could use a specially crafted Originate AMI request to execute arbitrary system commands.

The Asterisk project reports:

If Asterisk receives a re-invite initiating T.38 faxing and has a port of 0 and no c line in the SDP, a crash will occur.

The Asterisk project reports:

A SIP request can be sent to Asterisk that can change a SIP peers IP address. A REGISTER does not need to occur, and calls can be hijacked as a result. The only thing that needs to be known is the peers name; authentication details such as passwords do not need to be known. This vulnerability is only exploitable when the nat option is set to the default, or auto_force_rport.

The Gitea Team reports:

This release contains five security fixes, so we recommend updating:

• Fix issue with user.fullname
• Ignore mentions for users with no access
• Be more strict with git arguments
• Extract the username and password from the mirror url
• Reserve .well-known username

Squid Team reports:

Problem Description: Due to incorrect data management Squid is vulnerable to a information disclosure when processing HTTP Digest Authentication.

Severity: Nonce tokens contain the raw byte value of a pointer which sits within heap memory allocation. This information reduces ASLR protections and may aid attackers isolating memory areas to target for remote code execution attacks.

Sergey Poznyakoff reports:

The Gitea Team reports:

When a comment in an issue or PR mentions a user using @username, the mentioned user receives a mail notification even if they don't have permission to see the originating repository.

Matrix developers report:

Make sure that [...] events sent over /send_join, /send_leave, and /invite, are correctly signed and come from the expected servers.

The samba project reports:

Malicious servers can cause Samba client code to return filenames containing path separators to calling code.

When the password contains multi-byte (non-ASCII) characters, the check password script does not receive the full password string.

Users with the "get changes" extended access right can crash the AD DC LDAP server by requesting an attribute using the range= syntax.

Varnish Software reports:

A bug has been discovered in Varnish Cache where we fail to clear a pointer between the handling of one client requests and the next on the same connection. This can under specific circumstances lead to information being leaked from the connection workspace.

Todd C. Miller reports:

When sudo is configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification, it is possible to run commands as root by specifying the user ID -1 or 4294967295.

This can be used by a user with sufficient sudo privileges to run commands as root even if the Runas specification explicitly disallows root access as long as the ALL keyword is listed first in the Runas specification.

Log entries for commands run this way will list the target user as 4294967295 instead of root. In addition, PAM session modules will not be run for the command.

Problem Description:

The decompressor used in bzip2 contains a bug which can lead to an out-of-bounds write when processing a specially crafted bzip2(1) file.

bzip2recover contains a heap use-after-free bug which can be triggered when processing a specially crafted bzip2(1) file.

Impact:

An attacker who can cause maliciously crafted input to be processed may trigger either of these bugs. The bzip2recover bug may cause a crash, permitting a denial-of-service. The bzip2 decompressor bug could potentially be exploited to execute arbitrary code.

Note that some utilities, including the tar(1) archiver and the bspatch(1) binary patching utility (used in portsnap(8) and freebsd-update(8)) decompress bzip2(1)-compressed data internally; system administrators should assume that their systems will at some point decompress bzip2(1)-compressed data even if they never explicitly invoke the bunzip2(1) utility.

Problem Description:

The ICMPv6 input path incorrectly handles cases where an MLDv2 listener query packet is internally fragmented across multiple mbufs.

Impact:

A remote attacker may be able to cause an out-of-bounds read or write that may cause the kernel to attempt to access an unmapped page and subsequently panic.

Problem Description:

A function extracting the length from type-length-value encoding is not properly validating the submitted length.

Impact:

A remote user could cause, for example, an out-of-bounds read, decoding of unrelated data, or trigger a crash of the software such as bsnmpd resulting in a denial of service.

Problem Description:

The e1000 network adapters permit a variety of modifications to an Ethernet packet when it is being transmitted. These include the insertion of IP and TCP checksums, insertion of an Ethernet VLAN header, and TCP segmentation offload ("TSO"). The e1000 device model uses an on-stack buffer to generate the modified packet header when simulating these modifications on transmitted packets.

When TCP segmentation offload is requested for a transmitted packet, the e1000 device model used a guest-provided value to determine the size of the on-stack buffer without validation. The subsequent header generation could overflow an incorrectly sized buffer or indirect a pointer composed of stack garbage.

Impact:

A misbehaving bhyve guest could overwrite memory in the bhyve process on the host.

Problem Description:

Due do a missing check in the code of m_pulldown(9) data returned may not be contiguous as requested by the caller.

Impact:

Extra checks in the IPv6 code catch the error condition and trigger a kernel panic leading to a remote DoS (denial-of-service) attack with certain Ethernet interfaces. At this point it is unknown if any other than the IPv6 code paths can trigger a similar condition.

Problem Description:

The kernel driver for /dev/midistat implements a handler for read(2). This handler is not thread-safe, and a multi-threaded program can exploit races in the handler to cause it to copy out kernel memory outside the boundaries of midistat's data buffer.

Impact:

The races allow a program to read kernel memory within a 4GB window centered at midistat's data buffer. The buffer is allocated each time the device is opened, so an attacker is not limited to a static 4GB region of memory.

On 32-bit platforms, an attempt to trigger the race may cause a page fault in kernel mode, leading to a panic.

Problem Description:

System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file.

Impact:

A local user can use this flaw to obtain access to files, directories, sockets, etc., opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.

GitHub issue:

This issue has been created for public disclosure of an XSS vulnerability that was responsibly reported by https://hackerone.com/vxhex

In the Loofah gem, through v2.3.0, unsanitized JavaScript may occur in sanitized output when a crafted SVG element is republished.

bpo-38174: Update vendorized expat library version to 2.2.8, which resolves CVE-2019-15903.

bpo-37764: Fixes email._header_value_parser.get_unstructured going into an infinite loop for a specific case in which the email header does not have trailing whitespace, and the case in which it contains an invalid encoded word.

bpo-37461: Fix an infinite loop when parsing specially crafted email headers.

bpo-34155: Fix parsing of invalid email addresses with more than one @ (e.g. a@b@c.com.) to not return the part before 2nd @ as valid email address.

Mitre reports:

An issue was discovered in Pillow before 6.2.0. When reading specially crafted invalid image files, the library can either allocate very large amounts of memory or take an extremely long period of time to process the image.

mod_perl2 2.0.11 fixes Arbitrary Perl code execution in the context of the user account via a user-owned .htaccess.

mod_perl 2.0 through 2.0.10 allows attackers to execute arbitrary Perl code by placing it in a user-owned .htaccess file, because (contrary to the documentation) there is no configuration option that permits Perl code for the administrator's control of HTTP request processing without also permitting unprivileged users to run Perl code in the context of the user account that runs Apache HTTP Server processes.

Xpdf 4.02 fixes two vulnerabilities. Both fixes have been backported to 3.04.

An invalid memory access vulnerability in TextPage::findGaps() in Xpdf 4.01 through a crafted PDF document can cause a segfault.

An out of bounds write exists in TextPage::findGaps() of Xpdf 4.01.01

Unbound Security Advisories:

Due to an error in parsing NOTIFY queries, it is possible for Unbound to continue processing malformed queries and may ultimately result in a pointer dereference in uninitialized memory. This results in a crash of the Unbound daemon.

Sicheng Liu of Beijing DBSEC Technology Co., Ltd reports:

Incorrect scoping of kill operations in MongoDB Server's packaged SysV init scripts allow users with write access to the PID file to insert arbitrary PIDs to be killed when the root user stops the MongoDB process via SysV init.

Rich Mirch reports:

An unprivileged user or program on Microsoft Windows which can create OpenSSL configuration files in a fixed location may cause utility programs shipped with MongoDB server versions less than 4.0.11, 3.6.14, and 3.4.22 to run attacker defined code as the user running the utility.

Missing integrity hashes for CSS resources from CDNs

The Go project reports:

net/http (through net/textproto) used to accept and normalize invalid HTTP/1.1 headers with a space before the colon, in violation of RFC 7230. If a Go server is used behind a reverse proxy that accepts and forwards but doesn't normalize such invalid headers, the reverse proxy and the server can interpret the headers differently. This can lead to filter bypasses or request smuggling, the latter if requests from separate clients are multiplexed onto the same connection by the proxy. Such invalid headers are now rejected by Go servers, and passed without normalization to Go client applications.

Janos Follath reports:

Mbed TLS does not have a constant-time/constant-trace arithmetic library and uses blinding to protect against side channel attacks.

In the ECDSA signature routine previous Mbed TLS versions used the same RNG object for generating the ephemeral key pair and for generating the blinding values. The deterministic ECDSA function reused this by passing the RNG object created from the private key and the message to be signed as prescribed by RFC 6979. This meant that the same RNG object was used whenever the same message was signed, rendering the blinding ineffective.

If the victim can be tricked to sign the same message repeatedly, the private key may be recoverable through side channels.

Jon Siwek of Corelight reports:

This is a security patch release to address a potential Denial of Service vulnerability:

• The NTLM analyzer did not properly handle AV Pair sequences that were either empty or unterminated, resulting in invalid memory access or heap buffer over-read. The NTLM analyzer is enabled by default and used in the analysis of SMB, DCE/RPC, and GSSAPI protocols.

curl security problems:

CVE-2019-5481: FTP-KRB double-free

libcurl can be told to use kerberos over FTP to a server, as set with the CURLOPT_KRBLEVEL option.

During such kerberos FTP data transfer, the server sends data to curl in blocks with the 32 bit size of each block first and then that amount of data immediately following.

A malicious or just broken server can claim to send a very large block and if by doing that it makes curl's subsequent call to realloc() to fail, curl would then misbehave in the exit path and double-free the memory.

In practical terms, an up to 4 GB memory area may very well be fine to allocate on a modern 64 bit system but on 32 bit systems it will fail.

Kerberos FTP is a rarely used protocol with curl. Also, Kerberos authentication is usually only attempted and used with servers that the client has a previous association with.

CVE-2019-5482: TFTP small blocksize heap buffer overflow

libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that receives data from a TFTP server. It can call recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is controlled by the server.

This flaw is only triggered if the TFTP server sends an OACK without the BLKSIZE option, when a BLKSIZE smaller than 512 bytes was requested by the TFTP client. OACK is a TFTP extension and is not used by all TFTP servers.

Users choosing a smaller block size than default should be rare as the primary use case for changing the size is to make it larger.

It is rare for users to use TFTP across the Internet. It is most commonly used within local networks. TFTP as a protocol is always inherently insecure.

This issue was introduced by the add of the TFTP BLKSIZE option handling. It was previously incompletely fixed by an almost identical issue called CVE-2019-5436.

The OpenSSL project reports:

ECDSA remote timing attack (CVE-2019-1547) [Low]

Fork Protection (CVE-2019-1549) [Low]

(OpenSSL 1.1.1 only)

Adobe reports:

• This update resolves a same origin method execution vulnerability that could lead to arbitrary code execution (CVE-2019-8069).
• This update resolves a use-after-free vulnerability that could lead to arbitrary code execution (CVE-2019-8070).

Japheth Cleaver reports:

Several buffer overflows were reported by University of Cambridge Computer Security Incident Response Team.

A use-after-free in onig_new_deluxe() in regext.c in Oniguruma 6.9.2 allows attackers to potentially cause information disclosure, denial of service, or possibly code execution by providing a crafted regular expression. The attacker provides a pair of a regex pattern and a string, with a multi-byte encoding that gets handled by onig_new_deluxe().

A NULL Pointer Dereference in match_at() in regexec.c in Oniguruma 6.9.2 allows attackers to potentially cause denial of service by providing a crafted regular expression.

Oniguruma issues often affect Ruby, as well as common optional libraries for PHP and Rust.

Exim developers report:

If your Exim server accepts TLS connections, it is vulnerable. This does not depend on the TLS libray, so both, GnuTLS and OpenSSL are affected.

The vulnerability is exploitable by sending a SNI ending in a backslash-null sequence during the initial TLS handshake. The exploit exists as a POC. For more details see the document qualys.mbx

The Asterisk project reports:

When audio frames are given to the audio transcoding support in Asterisk the number of samples are examined and as part of this a message is output to indicate that no samples are present. A change was done to suppress this message for a particular scenario in which the message was not relevant. This change assumed that information about the origin of a frame will always exist when in reality it may not.

This issue presented itself when an RTP packet containing no audio (and thus no samples) was received. In a particular transcoding scenario this audio frame would get turned into a frame with no origin information. If this new frame was then given to the audio transcoding support a crash would occur as no samples and no origin information would be present. The transcoding scenario requires the genericplc option to be set to enabled (the default) and a transcoding path from the source format into signed linear and then from signed linear into another format.

Note that there may be other scenarios that have not been found which can cause an audio frame with no origin to be given to the audio transcoding support and thus cause a crash.

wordpress developers reports:

Props to Simon Scannell of RIPS Technologies for finding and disclosing two issues. The first, a cross-site scripting (XSS) vulnerability found in post previews by contributors. The second was a cross-site scripting vulnerability in stored comments.

CSRF protection tokens for anonymous users did not expire in some circumstances

Aki Tuomi reports:

Vulnerability Details: IMAP and ManageSieve protocol parsers do not properly handle NUL byte when scanning data in quoted strings, leading to out of bounds heap memory writes. Risk: This vulnerability allows for out-of-bounds writes to objects stored on the heap up to 8096 bytes in pre-login phase, and 65536 bytes post-login phase, allowing sufficiently skilled attacker to perform complicated attacks that can lead to leaking private information or remote code execution. Abuse of this bug is very difficult to observe, as it does not necessarily cause a crash. Attempts to abuse this bug are not directly evident from logs.

Jonathon Loomey of Netflix reports:

HTTP/2 implementations do not robustly handle abnormal traffic and resource exhaustion

Recently, a series of DoS attack vulnerabilities have been reported on a broad range of HTTP/2 stacks. Among the vulnerabilities, H2O is exposed to the following:

• CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
• CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
• CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

The Gitea Team reports:

This release contains two security fixes, so we highly recommend updating.

Node.js reports:

Node.js, as well as many other implementations of HTTP/2, have been found vulnerable to Denial of Service attacks. See https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for more information.

Updates are now available for all active Node.js release lines, including Linux ARMv6 builds for Node.js 8.x (which had been delayed).

We recommend that all Node.js users upgrade to a version listed below as soon as possible.

Vulnerabilities Fixed

Impact: All versions of Node.js 8 (LTS "Carbon"), Node.js 10 (LTS "Dubnium"), and Node.js 12 (Current) are vulnerable to the following:

• CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
• CVE-2019-9512 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
• CVE-2019-9513 "Resource Loop": The attacker creates multiple request streams and continually shuffles the priority of the streams in a way that causes substantial churn to the priority tree. This can consume excess CPU, potentially leading to a denial of service.
• CVE-2019-9514 "Reset Flood": The attacker opens a number of streams and sends an invalid request over each stream that should solicit a stream of RST_STREAM frames from the peer. Depending on how the peer queues the RST_STREAM frames, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
• CVE-2019-9515 "Settings Flood": The attacker sends a stream of SETTINGS frames to the peer. Since the RFC requires that the peer reply with one acknowledgement per SETTINGS frame, an empty SETTINGS frame is almost equivalent in behavior to a ping. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.
• CVE-2019-9516 "0-Length Headers Leak": The attacker sends a stream of headers with a 0-length header name and 0-length header value, optionally Huffman encoded into 1-byte or greater headers. Some implementations allocate memory for these headers and keep the allocation alive until the session dies. This can consume excess memory, potentially leading to a denial of service.
• CVE-2019-9517 "Internal Data Buffering": The attacker opens the HTTP/2 window so the peer can send without constraint; however, they leave the TCP window closed so the peer cannot actually write (many of) the bytes on the wire. The attacker then sends a stream of requests for a large response object. Depending on how the servers queue the responses, this can consume excess memory, CPU, or both, potentially leading to a denial of service.
• CVE-2019-9518 "Empty Frames Flood": The attacker sends a stream of frames with an empty payload and without the end-of-stream flag. These frames can be DATA, HEADERS, CONTINUATION and/or PUSH_PROMISE. The peer spends time processing each frame disproportionate to attack bandwidth. This can consume excess CPU, potentially leading to a denial of service. (Discovered by Piotr Sikora of Google)

Micah Snyder reports:

• An out of bounds write was possible within ClamAV&s NSIS bzip2 library when attempting decompression in cases where the number of selectors exceeded the max limit set by the library (CVE-2019-12900). The issue has been resolved by respecting that limit.
• The zip bomb vulnerability mitigated in 0.101.3 has been assigned the CVE identifier CVE-2019-12625. Unfortunately, a workaround for the zip-bomb mitigation was immediately identified. To remediate the zip-bomb scan time issue, a scan time limit has been introduced in 0.101.4. This limit now resolves ClamAV's vulnerability to CVE-2019-12625.

nvd.nist.gov reports

X.Org xdm 1.1.10, 1.1.11, and possibly other versions, when performing authentication using certain implementations of the crypt API function that can return NULL, allows remote attackers to cause a denial of service (NULL pointer dereference and crash) by attempting to log into an account whose password field contains invalid characters, as demonstrated using the crypt function from glibc 2.17 and later with (1) the "!" character in the salt portion of a password field or (2) a password that has been encrypted using DES or MD5 in FIPS-140 mode.

SO-AND-SO reports:

SECURITY: CVE-2019-10081

mod_http2: HTTP/2 very early pushes, for example configured with "H2PushResource", could lead to an overwrite of memory in the pushing request's pool, leading to crashes. The memory copied is that of the configured push link header values, not data supplied by the client.

SECURITY: CVE-2019-9517

Joe Cooper reports:

I've rolled out Webmin version 1.930 and Usermin version 1.780 for all repositories. This release includes several security fixes, including one potentially serious one caused by malicious code inserted into Webmin and Usermin at some point on our build infrastructure. We're still investigating how and when, but the exploitable code has never existed in our github repositories, so we've rebuilt from git source on new infrastructure (and checked to be sure the result does not contain the malicious code).

I don't have a changelog for these releases yet, but I wanted to announce them immediately due to the severity of this issue. To exploit the malicious code, your Webmin installation must have Webmin -> Webmin Configuration -> Authentication -> Password expiry policy set to Prompt users with expired passwords to enter a new one. This option is not set by default, but if it is set, it allows remote code execution.

This release addresses CVE-2019-15107, which was disclosed earlier today. It also addresses a handful of XSS issues that we were notified about, and a bounty was awarded to the researcher (a different one) who found them.

nghttp2 GitHub releases:

This release fixes CVE-2019-9511 "Data Dribble" and CVE-2019-9513 "Resource Loop" vulnerability in nghttpx and nghttpd. Specially crafted HTTP/2 frames cause Denial of Service by consuming CPU time. Check out https://github.com/Netflix/security-bulletins/blob/master/advisories/third-party/2019-002.md for details. For nghttpx, additionally limiting inbound traffic by --read-rate and --read-burst options is quite effective against this kind of attack.

CVE-2019-9511 "Data Dribble": The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

CVE-2019-9513 "Ping Flood": The attacker sends continual pings to an HTTP/2 peer, causing the peer to build an internal queue of responses. Depending on how efficiently this data is queued, this can consume excess CPU, memory, or both, potentially leading to a denial of service.

Apple reports:

• CVE-2019-8696 and CVE-2019-8675: SNMP buffer overflows.
• IPP buffer overflow.
• Memory disclosure in the scheduler.
• DoS issues in the scheduler.

The traefik project reports:

Update of dependency to go go1.12.8 resolves potential HTTP/2 denial of service in traefik.

Jesse Smith (upstream author of the doas program) reported:

Previous versions of "doas" transferred most environment variables, such as USER, HOME, and PATH from the original user to the target user. Passing these variables could cause files in the wrong path or home directory to be read (or written to), which resulted in potential security problems.

Many thanks to Sander Bos for reporting this issue and explaining how it can be exploited.

NGINX Team reports:

Several security issues were identified in nginx HTTP/2 implementation which might cause excessive memory consumption and CPU usage (CVE-2019-9511, CVE-2019-9513, CVE-2019-9516). The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the http2 option of the listen directive is used in a configuration file.

Nokogiri GitHub release:

A command injection vulnerability in Nokogiri v1.10.3 and earlier allows commands to be executed in a subprocess by Ruby's Kernel.open method. Processes are vulnerable only if the undocumented method Nokogiri::CSS::Tokenizer#load_file is being passed untrusted user input.

This vulnerability appears in code generated by the Rexical gem versions v1.0.6 and earlier. Rexical is used by Nokogiri to generate lexical scanner code for parsing CSS queries. The underlying vulnerability was addressed in Rexical v1.0.7 and Nokogiri upgraded to this version of Rexical in Nokogiri v1.10.4.

Jon Siwek of Corelight reports:

This is a security patch release to address potential Denial of Service vulnerabilities:

• Null pointer dereference in the RPC analysis code. RPC analyzers (e.g. MOUNT or NFS) are not enabled in the default configuration.
• Signed integer overflow in BinPAC-generated parser code. The result of this is Undefined Behavior with respect to the array bounds checking conditions that BinPAC generates, so it's unpredictable what an optimizing compiler may actually do under the assumption that signed integer overlows should never happen. The specific symptom which lead to finding this issue was with the PE analyzer causing out-of-memory crashes due to large allocations that were otherwise prevented when the array bounds checking logic was changed to prevent any possible signed integer overlow.

The KDE Community has released a security announcement:

The syntax Key[$e]=$(shell command) in *.desktop files, .directory files, and configuration files (typically found in ~/.config) was an intentional feature of KConfig, to allow flexible configuration. This could however be abused by malicious people to make the users install such files and get code executed even without intentional action by the user.

The PostgreSQL project reports:

Versions Affected: 9.4 - 11

Given a suitable `SECURITY DEFINER` function, an attacker can execute arbitrary SQL under the identity of the function owner. An attack requires `EXECUTE` permission on the function, which must itself contain a function call having inexact argument type match. For example, `length('foo'::varchar)` and `length('foo')` are inexact, while `length('foo'::text)` is exact. As part of exploiting this vulnerability, the attacker uses `CREATE DOMAIN` to create a type in a `pg_temp` schema. The attack pattern and fix are similar to that for CVE-2007-2138.

Writing `SECURITY DEFINER` functions continues to require following the considerations noted in the documentation:

https://www.postgresql.org/docs/devel/sql-createfunction.html#SQL-CREATEFUNCTION-SECURITY

Versions Affected: 11

In a database containing hypothetical, user-defined hash equality operators, an attacker could read arbitrary bytes of server memory. For an attack to become possible, a superuser would need to create unusual operators. It is possible for operators not purpose-crafted for attack to have the properties that enable an attack, but we are not aware of specific examples.

Django release notes:

CVE-2019-14232: Denial-of-service possibility in django.utils.text.Truncator

If django.utils.text.Truncator's chars() and words() methods were passed the html=True argument, they were extremely slow to evaluate certain inputs due to a catastrophic backtracking vulnerability in a regular expression. The chars() and words() methods are used to implement the truncatechars_html and truncatewords_html template filters, which were thus vulnerable

The regular expressions used by Truncator have been simplified in order to avoid potential backtracking issues. As a consequence, trailing punctuation may now at times be included in the truncated output.

CVE-2019-14233: Denial-of-service possibility in strip_tags()

Due to the behavior of the underlying HTMLParser, django.utils.html.strip_tags() would be extremely slow to evaluate certain inputs containing large sequences of nested incomplete HTML entities. The strip_tags() method is used to implement the corresponding striptags template filter, which was thus also vulnerable.

strip_tags() now avoids recursive calls to HTMLParser when progress removing tags, but necessarily incomplete HTML entities, stops being made.

Remember that absolutely NO guarantee is provided about the results of strip_tags() being HTML safe. So NEVER mark safe the result of a strip_tags() call without escaping it first, for example with django.utils.html.escape().

CVE-2019-14234: SQL injection possibility in key and index lookups for JSONField/HStoreField

Key and index lookups for JSONField and key lookups for HStoreField were subject to SQL injection, using a suitably crafted dictionary, with dictionary expansion, as the **kwargs passed to QuerySet.filter().

CVE-2019-14235: Potential memory exhaustion in django.utils.encoding.uri_to_iri()

If passed certain inputs, django.utils.encoding.uri_to_iri() could lead to significant memory usage due to excessive recursion when re-percent-encoding invalid UTF-8 octet sequences.

uri_to_iri() now avoids recursion when re-percent-encoding invalid UTF-8 octet sequences.

curl security problems:

CVE-2018-14618: NTLM password overflow via integer overflow

The internal function Curl_ntlm_core_mk_nt_hash multiplies the length of the password by two (SUM) to figure out how large temporary storage area to allocate from the heap.

The length value is then subsequently used to iterate over the password and generate output into the allocated storage buffer. On systems with a 32 bit size_t, the math to calculate SUM triggers an integer overflow when the password length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.

This bug is almost identical to CVE-2017-8816.

The Gitea Team reports:

This release contains two security fixes, so we highly recommend updating.

The Gitea Team reports:

This version of Gitea contains security fixes that could not be backported to 1.8. For this reason, we strongly recommend updating.

Problem Description:

If a process attempts to transmit rights over a UNIX-domain socket and an error causes the attempt to fail, references acquired on the rights are not released and are leaked. This bug can be used to cause the reference counter to wrap around and free the corresponding file structure.

Impact:

A local user can exploit the bug to gain root privileges or escape from a jail.

Problem Description:

To implement one particular ioctl, the Linux emulation code used a special interface present in the cd(4) driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd(4) device to arbitrarily overwrite kernel memory when some media is present in the device.

Impact:

A user in the operator group can make use of this interface to gain root privileges on a system with a cd(4) device when some media is present in the device.

Problem Description:

EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not to validate the received scalar and element values in EAP-pwd-Commit messages properly. This could result in attacks that would be able to complete EAP-pwd authentication exchange without the attacker having to know the used password.

See https://w1.fi/security/2019-4/eap-pwd-missing-commit-validation.txt for a detailed description of the bug.

Impact:

All wpa_supplicant and hostapd versions with EAP-pwd support.

Problem Description:

Insufficient validation of environment variables in the telnet client supplied in FreeBSD can lead to stack-based buffer overflows. A stack- based overflow is present in the handling of environment variables when connecting via the telnet client to remote telnet servers.

This issue only affects the telnet client. Inbound telnet sessions to telnetd(8) are not affected by this issue.

Impact:

These buffer overflows may be triggered when connecting to a malicious server, or by an active attacker in the network path between the client and server. Specially crafted TELNET command sequences may cause the execution of arbitrary code with the privileges of the user invoking telnet(1).

Problem Description:

A bug in the pf(4) IPv6 fragment reassembly logic incorrectly uses the last extension header offset from the last received packet instead of from the first packet.

Impact:

Malicious IPv6 packets with different IPv6 extensions could cause a kernel panic or potentially a filtering rule bypass.

Problem Description:

The code which handles a close(2) of a descriptor created by posix_openpt(2) fails to undo the configuration which causes SIGIO to be raised. This bug can lead to a write-after-free of kernel memory.

Impact:

The bug permits malicious code to trigger a write-after-free, which may be used to gain root privileges or escape a jail.

Problem Description:

States in pf(4) let ICMP and ICMP6 packets pass if they have a packet in their payload matching an existing condition. pf(4) does not check if the outer ICMP or ICMP6 packet has the same destination IP as the source IP of the inner protocol packet.

Impact:

A maliciously crafted ICMP/ICMP6 packet could bypass the packet filter rules and be passed to a host that would otherwise be unavailable.

Problem Description:

Due to insufficient initialization of memory copied to userland in the components listed above small amounts of kernel memory may be disclosed to userland processes.

Impact:

A user who can invoke 32-bit FreeBSD ioctls may be able to read the contents of small portions of kernel memory.

Such memory might contain sensitive information, such as portions of the file cache or terminal buffers. This information might be directly useful, or it might be leveraged to obtain elevated privileges in some way; for example, a terminal buffer might include a user-entered password.

Problem Description:

On some Intel processors utilizing speculative execution a local process may be able to infer stale information from microarchitectural buffers to obtain a memory disclosure.

Impact:

An attacker may be able to read secret data from the kernel or from a process when executing untrusted code (for example, in a web browser).

Network Time Foundation reports:

A crafted malicious authenticated mode 6 (ntpq) packet from a permitted network address can trigger a NULL pointer dereference, crashing ntpd.

Note that for this attack to work, the sending system must be on an address that the target's ntpd accepts mode 6 packets from, and must use a private key that is specifically listed as being used for mode 6 authorization.

Impact: The ntpd daemon can crash due to the NULL pointer dereference, causing a denial of service.

Mitigation:

• Use restrict noquery to limit addresses that can send mode 6 queries.
• Limit access to the private controlkey in ntp.keys.
• Upgrade to 4.2.8p13, or later.

Problem Description:

While processing acknowledgements, the RACK code uses several linked lists to maintain state entries. A malicious attacker can cause the lists to grow unbounded. This can cause an expensive list traversal on every packet being processed, leading to resource exhaustion and a denial of service.

Impact:

An attacker with the ability to send specially crafted TCP traffic to a victim system can degrade network performance and/or consume excessive CPU by exploiting the inefficiency of traversing the potentially very large RACK linked lists with relatively small bandwidth cost.

Problem Description:

System calls operating on file descriptors obtain a reference to relevant struct file which due to a programming error was not always put back, which in turn could be used to overflow the counter of affected struct file.

Impact:

A local user can use this flaw to obtain access to files, directories, sockets etc. opened by processes owned by other users. If obtained struct file represents a directory from outside of user's jail, it can be used to access files outside of the jail. If the user in question is a jailed root they can obtain root privileges on the host system.

Problem Description:

The pci_xhci_device_doorbell() function does not validate the 'epid' and 'streamid' provided by the guest, leading to an out-of-bounds read.

Impact:

A misbehaving bhyve guest could crash the system or access memory that it should not be able to.

Problem Description:

With certain inputs, iconv may write beyond the end of the output buffer.

Impact:

Depending on the way in which iconv is used, an attacker may be able to create a denial of service, provoke incorrect program behavior, or induce a remote code execution. iconv is a libc library function and the nature of possible attacks will depend on the way in which iconv is used by applications or daemons.

Problem Description:

A bug causes up to three bytes of kernel stack memory to be written to disk as uninitialized directory entry padding. This data can be viewed by any user with read access to the directory. Additionally, a malicious user with write access to a directory can cause up to 254 bytes of kernel stack memory to be exposed.

Impact:

Some amount of the kernel stack is disclosed and written out to the filesystem.

Matrix developers report:

The matrix team releases Synapse 1.2.1 as a critical security update. It contains patches relating to redactions and event federation:

• Prevent an attack where a federated server could send redactions for arbitrary events in v1 and v2 rooms.
• Prevent a denial-of-service attack where cycles of redaction events would make Synapse spin infinitely.
• Prevent an attack where users could be joined or parted from public rooms without their consent.
• Fix a vulnerability where a federated server could spoof read-receipts from users on other servers.
• It was possible for a room moderator to send a redaction for an m.room.create event, which would downgrade the room to version 1.

Exim team report:

A local or remote attacker can execute programs with root privileges - if you've an unusual configuration.

If your configuration uses the ${sort } expansion for items that can be controlled by an attacker (e.g. $local_part, $domain). The default config, as shipped by the Exim developers, does not contain ${sort }.

The vulnerability is exploitable either remotely or locally and could be used to execute other programs with root privilege. The ${sort } expansion re-evaluates its items.

Exim 4.92.1 is not vulnerable.

Simon Tatham reports:

Vulnerabilities fixed in this release include:

• A malicious SSH-1 server could trigger a buffer overrun by sending extremely short RSA keys, or certain bad packet length fields. Either of these could happen before host key verification, so even if you trust the server you *intended* to connect to, you would still be at risk.
  
  (However, the SSH-1 protocol is obsolete, and recent versions of PuTTY do not try it by default, so you are only at risk if you work with old servers and have explicitly configured SSH-1.)
• If a malicious process found a way to impersonate Pageant, then it could cause an integer overflow in any of the SSH client tools (PuTTY, Plink, PSCP, PSFTP) which accessed the malicious Pageant.

Other security-related bug fixes include:

• The 'trust sigil' system introduced in PuTTY 0.71 to protect against server spoofing attacks had multiple bugs. Trust sigils were not turned off after login in the SSH-1 and Rlogin protocols, and not turned back on if you used the Restart Session command. Both are now fixed.

Mitre report:

libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.

The Asterisk project reports:

A specially crafted SIP in-dialog MESSAGE message can cause Asterisk to crash.

Python changelog:

bpo-37463: ssl.match_hostname() no longer accepts IPv4 addresses with additional text after the address and only quad-dotted notation without trailing whitespaces. Some inet_aton() implementations ignore whitespace and all data after whitespace, e.g.'127.0.0.1 whatever'.

bpo-35907: CVE-2019-9948: Avoid file reading by disallowing local-file:// and local_file:// URL schemes in URLopener().open() and URLopener().retrieve() of urllib.request.

bpo-36742: Fixes mishandling of pre-normalization characters in urlsplit().

bpo-30458: Address CVE-2019-9740 by disallowing URL paths with embedded whitespace or control characters through into the underlying http client request. Such potentially malicious header injection URLs now cause an http.client.InvalidURL exception to be raised.

bpo-33529: Prevent fold function used in email header encoding from entering infinite loop when there are too many non-ASCII characters in a header.

bpo-35755: shutil.which() now uses os.confstr("CS_PATH") if available and if the PATH environment variable is not set. Remove also the current directory from posixpath.defpath. On Unix, shutil.which() and the subprocess module no longer search the executable in the current directory if the PATH environment variable is not set.

The Asterisk project reports:

When T.38 faxing is done in Asterisk a T.38 reinvite may be sent to an endpoint to switch it to T.38. If the endpoint responds with an improperly formatted SDP answer including both a T.38 UDPTL stream and an audio or video stream containing only codecs not allowed on the SIP peer or user a crash will occur. The code incorrectly assumes that there will be at least one common codec when T.38 is also in the SDP answer.

libssh2 developers report:

• Defend against possible integer overflows in comp_method_zlib_decomp.
• Defend against writing beyond the end of the payload in _libssh2_transport_read().
• Sanitize padding_length - _libssh2_transport_read().
• This prevents an underflow resulting in a potential out-of-bounds read if a server sends a too-large padding_length, possibly with malicious intent.
• Prevent zero-byte allocation in sftp_packet_read() which could lead to an out-of-bounds read.
• Check the length of data passed to sftp_packet_add() to prevent out-of-bounds reads.
• Add a required_size parameter to sftp_packet_require et. al. to require callers of these functions to handle packets that are too short.
• Additional length checks to prevent out-of-bounds reads and writes in _libssh2_packet_add().

The PostgreSQL project reports:

An authenticated user could create a stack-based buffer overflow by changing their own password to a purpose-crafted value. In addition to the ability to crash the PostgreSQL server, this could be further exploited to execute arbitrary code as the PostgreSQL operating system account.

Additionally, a rogue server could send a specifically crafted message during the SCRAM authentication process and cause a libpq-enabled client to either crash or execute arbitrary code as the client's operating system account.

This issue is fixed by upgrading and restarting your PostgreSQL server as well as your libpq installations. All users running PostgreSQL 10, 11, and 12 beta are encouraged to upgrade as soon as possible.

The phpMyAdmin development team reports:

Summary

CSRF vulnerability in login form

Description

A vulnerability was found that allows an attacker to trigger a CSRF attack against a phpMyAdmin user. The attacker can trick the user, for instance through a broken tag pointing at the victim's phpMyAdmin database, and the attacker can potentially deliver a payload (such as a specific INSERT or DELETE statement) through the victim.

Severity

We consider this vulnerability to be severe.

Mitigation factor

Only the 'cookie' auth_type is affected; users can temporary use phpMyAdmin's http authentication as a workaround.

Security releases for Vim/NeoVim:

CVE-2019-11831: By-passing protection of Phar Stream Wrapper Interceptor.

In order to intercept file invocations like file_exists or stat on compromised Phar archives the base name has to be determined and checked before allowing to be handled by PHP Phar stream handling. The current implementation is vulnerable to path traversal leading to scenarios where the Phar archive to be assessed is not the actual (compromised) file.

We received a report of a possible remote exploit. Currently there is no evidence of an active use of this exploit.

A patch exists already, is being tested, and backported to all versions we released since (and including) 4.87.

The severity depends on your configuration. It depends on how close to the standard configuration your Exim runtime configuration is. The closer the better.

Exim 4.92 is not vulnerable.

Buildbot accepted user-submitted authorization token from OAuth and used it to authenticate user.

The vulnerability can lead to malicious attackers to authenticate as legitimate users of a Buildbot instance without knowledge of the victim's login credentials on certain scenarios.

If an attacker has an application authorized to access data of another user at the same Identity Provider as the used by the Buildbot instance, then he can acquire a token to access the data of that user, supply the token to the Buildbot instance and successfully login as the victim.

Jon Siwek of Corelight reports:

The following Denial of Service vulnerabilities are addressed:

• Integer type mismatches in BinPAC-generated parser code and Bro analyzer code may allow for crafted packet data to cause unintentional code paths in the analysis logic to be taken due to unsafe integer conversions causing the parser and analysis logic to each expect different fields to have been parsed. One such example, reported by Maksim Shudrak, causes the Kerberos analyzer to dereference a null pointer. CVE-2019-12175 was assigned for this issue.
• The Kerberos parser allows for several fields to be left uninitialized, but they were not marked with an &optional attribute and several usages lacked existence checks. Crafted packet data could potentially cause an attempt to access such uninitialized fields, generate a runtime error/exception, and leak memory. Existence checks and &optional attributes have been added to the relevent Kerberos fields.
• BinPAC-generated protocol parsers commonly contain fields whose length is derived from other packet input, and for those that allow for incremental parsing, BinPAC did not impose a limit on how large such a field could grow, allowing for remotely-controlled packet data to cause growth of BinPAC's flowbuffer bounded only by the numeric limit of an unsigned 64-bit integer, leading to memory exhaustion. There is now a generalized limit for how large flowbuffers are allowed to grow, tunable by setting "BinPAC::flowbuffer_capacity_max".

Cyrus IMAP 3.0.10 Release Notes states:

Fixed CVE-2019-11356: buffer overrun in httpd

MITRE reports:

An exploitable use after free vulnerability exists in the window function functionality of Sqlite3 3.26.0. A specially crafted SQL command can cause a use after free vulnerability, potentially resulting in remote code execution. An attacker can send a malicious SQL command to trigger this vulnerability.

Mitre reports:

An issue was discovered in Suricata 4.1.x before 4.1.4. If the input of the function SSHParseBanner is composed only of a \n character, then the program runs into a heap-based buffer over-read. This occurs because the erroneous search for \r results in an integer underflow.

MITRE:

Serendipity before 2.1.5 has XSS via EXIF data that is mishandled in the templates/2k11/admin/media_choose.tpl Editor Preview feature or the templates/2k11/admin/media_items.tpl Media Library feature.

OCaml before 4.03.0 does not properly handle sign extensions, which allows remote attackers to conduct buffer overflow attacks or obtain sensitive information as demonstrated by a long string to the String.copy function.

Aki Tuomi reports:

* CVE-2019-10691: Trying to login with 8bit username containing invalid UTF8 input causes auth process to crash if auth policy is enabled. This could be used rather easily to cause a DoS. Similar crash also happens during mail delivery when using invalid UTF8 in From or Subject header when OX push notification driver is used.

curl security problems:

CVE-2019-5435: Integer overflows in curl_url_set()

libcurl contains two integer overflows in the curl_url_set() function that if triggered, can lead to a too small buffer allocation and a subsequent heap buffer overflow.

The flaws only exist on 32 bit architectures and require excessive string input lengths.

CVE-2019-5436: TFTP receive buffer overflow

libcurl contains a heap buffer overflow in the function (tftp_receive_packet()) that recevives data from a TFTP server. It calls recvfrom() with the default size for the buffer rather than with the size that was used to allocate it. Thus, the content that might overwrite the heap memory is entirely controlled by the server.

The flaw exists if the user selects to use a "blksize" of 504 or smaller (default is 512). The smaller size that is used, the larger the possible overflow becomes.

Users chosing a smaller size than default should be rare as the primary use case for changing the size is to make it larger.

It is rare for users to use TFTP across the Internet. It is most commonly used within local networks.

Sean McArthur reports:

The Rust Programming Language Standard Library 1.34.x before 1.34.2 contains a stabilized method which, if overridden, can violate Rust's safety guarantees and cause memory unsafety. If the Error::type_id method is overridden then any type can be safely cast to any other type, causing memory safety vulnerabilities in safe code (e.g., out-of-bounds write or read). Code that does not manually implement Error::type_id is unaffected.

Heap-buffer-overflow in exif_iif_add_value (CVE-2019-11035)

The PostgreSQL project reports:

PostgreSQL maintains statistics for tables by sampling data available in columns; this data is consulted during the query planning process. Prior to this release, a user able to execute SQL queries with permissions to read a given column could craft a leaky operator that could read whatever data had been sampled from that column. If this happened to include values from rows that the user is forbidden to see by a row security policy, the user could effectively bypass the policy. This is fixed by only allowing a non-leakproof operator to use this data if there are no relevant row security policies for the table.

The PostgreSQL project reports:

Prior to this release, a user running PostgreSQL 11 can read arbitrary bytes of server memory by executing a purpose-crafted INSERT statement to a partitioned table.

Gitea Team reports:

This release contains two new security fixes which cannot be backported to the 1.7.0 branch, so it is recommended to update to this version.

jQuery 3.4.0 includes a fix for some unintended behavior when using jQuery.extend(true, {}, ...). If an unsanitized source object contained an enumerable __proto__ property, it could extend the native Object.prototype. This fix is included in jQuery 3.4.0, but patch diffs exist to patch previous jQuery versions.

It's possible that this vulnerability is exploitable with some Drupal modules. As a precaution, this Drupal security release backports the fix to jQuery.extend(), without making any other changes to the jQuery version that is included in Drupal core (3.2.1 for Drupal 8 and 1.4.4 for Drupal 7) or running on the site via some other module such as jQuery Update.

Problem Description:

Potential side channel attacks in the SAE implementations used by both hostapd and wpa_supplicant (see CVE-2019-9494 and VU#871675). EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there is no reason to believe that the EAP-pwd implementation would be immune against the type of cache attack that was identified for the SAE implementation. Since the EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not support MODP groups, the timing attack described against SAE is not applicable for the EAP-pwd implementation.

See https://w1.fi/security/2019-2/eap-pwd-side-channel-attack.txt for a detailed description of the bug.

Impact:

All wpa_supplicant and hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration).

Problem Description:

Side channel attacks in the SAE implementations used by both hostapd (AP) and wpa_supplicant (infrastructure BSS station/mesh station). SAE (Simultaneous Authentication of Equals) is also known as WPA3-Personal. The discovered side channel attacks may be able to leak information about the used password based on observable timing differences and cache access patterns. This might result in full password recovery when combined with an offline dictionary attack and if the password is not strong enough to protect against dictionary attacks.

See https://w1.fi/security/2019-1/sae-side-channel-attacks.txt for a detailed description of the bug.

Impact:

All wpa_supplicant and hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).

Problem Description:

When hostapd is used to operate an access point with SAE (Simultaneous Authentication of Equals; also known as WPA3-Personal), an invalid authentication sequence could result in the hostapd process terminating due to a NULL pointer dereference when processing SAE confirm message. This was caused by missing state validation steps when processing the SAE confirm message in hostapd/AP mode.

See https://w1.fi/security/2019-3/sae-confirm-missing-state-validation.txt for a detailed description of the bug.

Impact:

All hostapd versions with SAE support (CONFIG_SAE=y in the build configuration and SAE being enabled in the runtime configuration).

Problem Description:

EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not to validate fragmentation reassembly state properly for a case where an unexpected fragment could be received. This could result in process termination due to NULL pointer dereference.

See https://w1.fi/security/2019-5/eap-pwd-message-reassembly-issue-with-unexpected-fragment.txt for a detailed description of the bug.

Impact:

All wpa_supplicant and hostapd versions with EAP-pwd support could suffer a denial of service attack through process termination.

These vulnerabilities impact Istio features that rely on Envoy to enforce any of authorization, routing, or rate limiting.

Jupyter blog:

Login pages tend to take a parameter for redirecting back to a page after successful login, e.g. /login?next=/notebooks/mynotebook.ipynb, so that you aren't disrupted too much if you try to visit a page, but have to authenticate first. An Open Redirect Vulnerability is when a malicious person crafts a link pointing to the login page of a trusted site, but setting the "redirect after successful login" parameter to send the user to their own site, instead of a page on the authenticated site (the notebook or JupyterHub server), e.g. /login?next=http://badwebsite.biz. This doesn't necessarily compromise anything immediately, but it enables phishing if users don't notice that the domain has changed, e.g. by showing a fake "re-enter your password" page. Servers generally have to validate the redirect URL to avoid this. Both JupyterHub and Notebook already do this, but the validation didn't take into account all possible ways to redirect to other sites, so some malicious URLs could still be crafted to redirect away from the server (the above example does not work in any recent version of either package). Only certain browsers (Chrome and Firefox, not Safari) could be redirected from the JupyterHub login page, but all browsers could be redirected away from a standalone notebook server.

Aki Tuomi reports:

Vulnerability Details: When reading FTS or POP3-UIDL header from dovecot index, the input buffer size is not bound, and data is copied to target structure causing stack overflow. Risk: This can be used for local root privilege escalation or executing arbitrary code in dovecot process context. This requires ability to directly modify dovecot indexes. Steps to reproduce: Produce dovecot.index.log entry that creates an FTS header which has more than 12 bytes of data. Trigger dovecot indexer-worker or run doveadm index. Dovecot will crash. Mitigations: Since 2.3.0 dovecot has been compiled with stack smash protection, ASLR, read-only GOT tables and other techniques that make exploiting this bug much harder.

An issue has been found in PowerDNS Authoritative Server when the HTTP remote backend is used in RESTful mode (without post=1 set), allowing a remote user to cause the HTTP backend to connect to an attacker-specified host instead of the configured one, via a crafted DNS query. This can be used to cause a denial of service by preventing the remote backend from getting a response, content spoofing if the attacker can time its own query so that subsequent queries will use an attacker-controlled HTTP server instead of the configured one, and possibly information disclosure if the Authoritative Server has access to internal servers.

The OpenSSL project reports:

0-byte record padding oracle (CVE-2019-1559) (Moderate)

If an application encounters a fatal protocol error and then calls SSL_shutdown() twice (once to send a close_notify, and once to receive one) then OpenSSL can respond differently to the calling application if a 0 byte record is received with invalid padding compared to if a 0 byte record is received with an invalid MAC. If the application then behaves differently based on that in a way that is detectable to the remote peer, then this amounts to a padding oracle that could be used to decrypt data.

The OpenSSL project reports:

Low: ChaCha20-Poly1305 with long nonces (CVE-2019-1543)

ChaCha20-Poly1305 is an AEAD cipher, and requires a unique nonce input for every encryption operation. RFC 7539 specifies that the nonce value (IV) should be 96 bits (12 bytes). OpenSSL allows a variable nonce length and front pads the nonce with 0 bytes if it is less than 12 bytes. However it also incorrectly allows a nonce to be set of up to 16 bytes. In this case only the last 12 bytes are significant and any additional leading bytes are ignored.

Node.js reports:

Updates are now available for all active Node.js release lines. In addition to fixes for security flaws in Node.js, they also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2r which contains a fix for a moderate severity security vulnerability.

For these releases, we have decided to withhold the fix for the Misinterpretation of Input (CWE-115) flaw mentioned in the original announcement. This flaw is very low severity and we are not satisfied that we had a complete and stable fix ready for release. We will be seeking to address this flaw via alternate mechanisms in the near future. In addition, we have introduced an additional CVE for a change in Node.js 6 that we have decided to classify as a Denial of Service (CWE-400) flaw.

We recommend that all Node.js users upgrade to a version listed below as soon as possible.

OpenSSL: 0-byte record padding oracle (CVE-2019-1559)

OpenSSL 1.0.2r contains a fix for CVE-2019-1559 and is included in the releases for Node.js versions 6 and 8 only. Node.js 10 and 11 are not impacted by this vulnerability as they use newer versions of OpenSSL which do not contain the flaw.

Under certain circumstances, a TLS server can be forced to respond differently to a client if a zero-byte record is received with an invalid padding compared to a zero-byte record with an invalid MAC. This can be used as the basis of a padding oracle attack to decrypt data.

Only TLS connections using certain ciphersuites executing under certain conditions are exploitable. We are currently unable to determine whether the use of OpenSSL in Node.js exposes this vulnerability. We are taking a cautionary approach and recommend the same for users. For more information, see the advisory and a detailed write-up by the reporters of the vulnerability.

CVE-2018-5785 was fixed in r480624.

CVE-2018-6616 was fixed in r489415.

Problem Description:

The callee-save registers are used by kernel and for some of them (%r8, %r10, and for non-PTI configurations, %r9) the content is not sanitized before return from syscalls, potentially leaking sensitive information.

Impact:

Typically an address of some kernel data structure used in the syscall implementation, is exposed.

Problem Description:

FreeBSD 12.0 attempts to handle the case where the receiving process does not provide a sufficiently large buffer for an incoming control message containing rights. In particular, to avoid leaking the corresponding descriptors into the receiving process' descriptor table, the kernel handles the truncation case by closing descriptors referenced by the discarded message.

The code which performs this operation failed to release a reference obtained on the file corresponding to a received right. This bug can be used to cause the reference counter to wrap around and free the file structure.

Impact:

A local user can exploit the bug to gain root privileges or escape from a jail.

curl security problems:

CVE-2018-16890: NTLM type-2 out-of-bounds buffer read

libcurl contains a heap buffer out-of-bounds read flaw.

The function handling incoming NTLM type-2 messages (lib/vauth/ntlm.c:ntlm_decode_type2_target) does not validate incoming data correctly and is subject to an integer overflow vulnerability.

Using that overflow, a malicious or broken NTLM server could trick libcurl to accept a bad length + offset combination that would lead to a buffer read out-of-bounds.

CVE-2019-3822: NTLMv2 type-3 header stack buffer overflow

libcurl contains a stack based buffer overflow vulnerability.

The function creating an outgoing NTLM type-3 header (lib/vauth/ntlm.c:Curl_auth_create_ntlm_type3_message()), generates the request HTTP header contents based on previously received data. The check that exists to prevent the local buffer from getting overflowed is implemented wrongly (using unsigned math) and as such it does not prevent the overflow from happening.

This output data can grow larger than the local buffer if very large "nt response" data is extracted from a previous NTLMv2 header provided by the malicious or broken HTTP server.

Such a "large value" needs to be around 1000 bytes or more. The actual payload data copied to the target buffer comes from the NTLMv2 type-2 response header.

CVE-2019-3823: SMTP end-of-response out-of-bounds read

libcurl contains a heap out-of-bounds read in the code handling the end-of-response for SMTP.

If the buffer passed to smtp_endofresp() isn't NUL terminated and contains no character ending the parsed number, and len is set to 5, then the strtol() call reads beyond the allocated buffer. The read contents will not be returned to the caller.

Gitlab reports:

Leak of Confidential Issue and Merge Request Titles

Persistent XSS in User Status

Aki Tuomi (Open-Xchange Oy) reports:

Normally Dovecot is configured to authenticate imap/pop3/managesieve/submission clients using regular username/password combination. Some installations have also required clients to present a trusted SSL certificate on top of that. It's also possible to configure Dovecot to take the username from the certificate instead of from the user provided authentication. It's also possible to avoid having a password at all, only trusting the SSL certificate. If the provided trusted SSL certificate is missing the username field, Dovecot should be failing the authentication. However, the earlier versions will take the username from the user provided authentication fields (e.g. LOGIN command). If there is no additional password verification, this allows the attacker to login as anyone else in the system. This affects only installations using: auth_ssl_require_client_cert = yes auth_ssl_username_from_cert = yes Attacker must also have access to a valid trusted certificate without the ssl_cert_username_field in it. The default is commonName, which almost certainly exists in all certificates. This could happen for example if ssl_cert_username_field is a field that normally doesn't exist, and attacker has access to a web server's certificate (and key), which is signed with the same CA. Attack can be migitated by having the certificates with proper Extended Key Usage, such as 'TLS Web Server' and 'TLS Web Server Client'. Also, ssl_cert_username_field setting was ignored with external SMTP AUTH, because none of the MTAs (Postfix, Exim) currently send the cert_username field. This may have allowed users with trusted certificate to specify any username in the authentication. This does not apply to Dovecot Submission service.

They will be exposed very soon..

The phpMyAdmin development team reports:

Summary

Arbitrary file read vulnerability

Description

When AllowArbitraryServer configuration set to true, with the use of a rogue MySQL server, an attacker can read any file on the server that the web server's user can access.

phpMyadmin attempts to block the use of LOAD DATA INFILE, but due to a bug in PHP, this check is not honored. Additionally, when using the 'mysql' extension, mysql.allow_local_infile is enabled by default. Both of these conditions allow the attack to occur.

Severity

We consider this vulnerability to be critical.

Mitigation factor

This attack can be mitigated by setting the `AllowArbitraryServer` configuration directive to false (which is the default value).

Affected Versions

phpMyAdmin versions from at least 4.0 through 4.8.4 are affected

Summary

SQL injection in Designer feature

Description

A vulnerability was reported where a specially crafted username can be used to trigger an SQL injection attack through the designer feature.

Severity

We consider this vulnerability to be serious.

Affected Versions

phpMyAdmin versions from 4.5.0 through 4.8.4 are affected

The Requests package before 2.20.0 for Python sends an HTTP Authorization header to an http URI upon receiving a same-hostname https-to-http redirect, which makes it easier for remote attackers to discover credentials by sniffing the network.

Older releases are not affected. NOTE: The attacker needs to know in advance valid addresses in the peer's memory to jump to, so measures like ASLR are effective mitigations. NOTE: this attack can only take place after authentication, so peers behind CURVE/GSSAPI are not vulnerable to unauthenticated attackers.

Drupal Security Team reports:

A remote code execution vulnerability exists in PHP's built-in phar stream wrapper when performing file operations on an untrusted phar:// URI.

Some Drupal code (core, contrib, and custom) may be performing file operations on insufficiently validated user input, thereby being exposed to this vulnerability.

This vulnerability is mitigated by the fact that such code paths typically require access to an administrative permission or an atypical configuration.

Helm security notice

A specially crafted chart may be able to unpack content into locations on the filesystem outside of the chart's path, potentially overwriting existing files.

The Shibboleth Consortium reports:

SAML messages, assertions, and metadata all commonly contain date/time information in a standard XML format.

Invalid formatted data in such fields cause an exception of a type that was not handled properly in the V3 software and causes a crash (usually to the shibd daemon process, but possibly to Apache in rare cases). Note that the crash occurs prior to evaluation of a message's authenticity, so can be exploited by an untrusted attacker.

The problem is believed to be specific to the V3 software and would not cause a crash in the older, now unsupported, V2 software.

Bro Network security Monitor reports:

Bro 2.6.1 updates the embedded SQLite to version 3.26.0 to address the "Magellan" remote code execution vulnerability. The stock Bro configuration/scripts don't use SQLite by default, but custom user scripts/packages may.

Problem Description:

Due to insufficient validation of network-provided data it may be possible for a malicious attacker to craft a bootp packet which could cause a stack buffer overflow.

Impact:

It is possible that the buffer overflow could lead to a Denial of Service or remote code execution.

wordpress developers reports:

WordPress versions 5.0 and earlier are affected by the following bugs, which are fixed in version 5.0.1. Updated versions of WordPress 4.9 and older releases are also available, for users who have not yet updated to 5.0.

Karim El Ouerghemmi discovered that authors could alter meta data to delete files that they weren?t authorized to.

Simon Scannell of RIPS Technologies discovered that authors could create posts of unauthorized post types with specially crafted input.

Sam Thomas discovered that contributors could craft meta data in a way that resulted in PHP object injection.

Tim Coen discovered that contributors could edit new comments from higher-privileged users, potentially leading to a cross-site scripting vulnerability.

Tim Coen also discovered that specially crafted URL inputs could lead to a cross-site scripting vulnerability in some circumstances. WordPress itself was not affected, but plugins could be in some situations.

Team Yoast discovered that the user activation screen could be indexed by search engines in some uncommon configurations, leading to exposure of email addresses, and in some rare cases, default generated passwords.

Tim Coen and Slavco discovered that authors on Apache-hosted sites could upload specifically crafted files that bypass MIME verification, leading to a cross-site scripting vulnerability.

Janos Follath reports:

Typo3 core team reports:

CKEditor 4.11 fixes an XSS vulnerability in the HTML parser reported by maxarr. The vulnerability stemmed from the fact that it was possible to execute XSS inside the CKEditor source area after persuading the victim to: (i) switch CKEditor to source mode, then (ii) paste a specially crafted HTML code, prepared by the attacker, into the opened CKEditor source area, and (iii) switch back to WYSIWYG mode. Although this is an unlikely scenario, we recommend to upgrade to the latest editor version.

Failing to properly encode user input, online media asset rendering (*.youtube and *.vimeo files) is vulnerable to cross-site scripting. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.

Failing to properly encode user input, notifications shown in modal windows in the TYPO3 backend are vulnerable to cross-site scripting. A valid backend user account is needed in order to exploit this vulnerability.

Failing to properly encode user input, login status display is vulnerable to cross-site scripting in the website frontend. A valid user account is needed in order to exploit this vulnerability - either a backend user or a frontend user having the possibility to modify their user profile.

Template patterns that are affected are:

• ###FEUSER_[fieldName]### using system extension felogin
• for regular frontend rendering (pattern can be defined individually using TypoScript setting config.USERNAME_substToken)

It has been discovered that cookies created in the Install Tool are not hardened to be submitted only via HTTP. In combination with other vulnerabilities such as cross-site scripting it can lead to hijacking an active and valid session in the Install Tool.

The Install Tool exposes the current TYPO3 version number to non-authenticated users.

Online Media Asset Handling (*.youtube and *.vimeo files) in the TYPO3 backend is vulnerable to denial of service. Putting large files with according file extensions results in high consumption of system resources. This can lead to exceeding limits of the current PHP process which results in a dysfunctional backend component. A valid backend user account or write access on the server system (e.g. SFTP) is needed in order to exploit this vulnerability.

TYPO3?s built-in record registration functionality (aka ?basic shopping cart?) using recs URL parameters is vulnerable to denial of service. Failing to properly ensure that anonymous user sessions are valid, attackers can use this vulnerability in order to create an arbitrary amount of individual session-data records in the database.

Apache CouchDB PMC reports:

Database Administrator could achieve privilege escalation to the account that CouchDB runs under, by abusing insufficient validation in the HTTP API, escaping security controls implemented in previous releases.

The phpMyAdmin development team reports:

Summary

Local file inclusion through transformation feature

Description

A flaw has been found where an attacker can exploit phpMyAdmin to leak the contents of a local file. The attacker must have access to the phpMyAdmin Configuration Storage tables, although these can easily be created in any database to which the attacker has access. An attacker must have valid credentials to log in to phpMyAdmin; this vulnerability does not allow an attacker to circumvent the login system.

Severity

We consider this vulnerability to be severe.

Summary

XSRF/CSRF vulnerability in phpMyAdmin

Description

By deceiving a user to click on a crafted URL, it is possible to perform harmful SQL operations such as renaming databases, creating new tables/routines, deleting designer pages, adding/deleting users, updating user passwords, killing SQL processes, etc.

Severity

We consider this vulnerability to be of moderate severity.

Summary

XSS vulnerability in navigation tree

Description

A Cross-Site Scripting vulnerability was found in the navigation tree, where an attacker can deliver a payload to a user through a specially-crafted database/table name.

Severity

We consider this attack to be of moderate severity.

Mitigation factor

The stored XSS vulnerabilities can be triggered only by someone who logged in to phpMyAdmin, as the usual token protection prevents non-logged-in users from accessing the required forms.

Problem Description:

Insufficient and improper checking in the NFS server code could cause a denial of service or possibly remote code execution via a specially crafted network packet.

Impact:

A remote attacker could cause the NFS server to crash, resulting in a denial of service, or possibly execute arbitrary code on the server.

Node.js reports:

Updates are now available for all active Node.js release lines. These include fixes for the vulnerabilities identified in the initial announcement. They also include upgrades of Node.js 6 and 8 to OpenSSL 1.0.2q, and upgrades of Node.js 10 and 11 to OpenSSL 1.1.0j.

We recommend that all Node.js users upgrade to a version listed below as soon as possible.

Debugger port 5858 listens on any interface by default (CVE-2018-12120)

All versions of Node.js 6 are vulnerable and the severity is HIGH. When the debugger is enabled with node --debug or node debug, it listens to port 5858 on all interfaces by default. This may allow remote computers to attach to the debug port and evaluate arbitrary JavaScript. The default interface is now localhost. It has always been possible to start the debugger on a specific interface, such as node --debug=localhost. The debugger was removed in Node.js 8 and replaced with the inspector, so no versions from 8 and later are vulnerable.

Denial of Service with large HTTP headers (CVE-2018-12121)

All versions of 6 and later are vulnerable and the severity is HIGH. By using a combination of many requests with maximum sized headers (almost 80 KB per connection), and carefully timed completion of the headers, it is possible to cause the HTTP server to abort from heap allocation failure. Attack potential is mitigated by the use of a load balancer or other proxy layer.

The total size of HTTP headers received by Node.js now must not exceed 8192 bytes.

"Slowloris" HTTP Denial of Service (CVE-2018-12122)

All versions of Node.js 6 and later are vulnerable and the severity is LOW. An attacker can cause a Denial of Service (DoS) by sending headers very slowly keeping HTTP or HTTPS connections and associated resources alive for a long period of time. Attack potential is mitigated by the use of a load balancer or other proxy layer.

A timeout of 40 seconds now applies to servers receiving HTTP headers. This value can be adjusted with server.headersTimeout. Where headers are not completely received within this period, the socket is destroyed on the next received chunk. In conjunction with server.setTimeout(), this aids in protecting against excessive resource retention and possible Denial of Service.

Hostname spoofing in URL parser for javascript protocol (CVE-2018-12123)

All versions of Node.js 6 and later are vulnerable and the severity is LOW. If a Node.js application is using url.parse() to determine the URL hostname, that hostname can be spoofed by using a mixed case "javascript:" (e.g. "javAscript:") protocol (other protocols are not affected). If security decisions are made about the URL based on the hostname, they may be incorrect.

HTTP request splitting (CVE-2018-12116)

Node.js 6 and 8 are vulnerable and the severity is MEDIUM. If Node.js can be convinced to use unsanitized user-provided Unicode data for the path option of an HTTP request, then data can be provided which will trigger a second, unexpected, and user-defined HTTP request to made to the same server.

OpenSSL Timing vulnerability in ECDSA signature generation (CVE-2018-0735)

The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.

OpenSSL Timing vulnerability in DSA signature generation (CVE-2018-0734)

The OpenSSL DSA signature algorithm has been shown to be vulnerable to a timing side-channel attack. An attacker could use variations in the signing algorithm to recover the private key.

OpenSSL Microarchitecture timing vulnerability in ECC scalar multiplication (CVE-2018-5407)

OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side-channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.

Problem Description:

Insufficient bounds checking in one of the device models provided by bhyve(8) can permit a guest operating system to overwrite memory in the bhyve(8) processing possibly permitting arbitary code execution.

Impact:

A guest OS using a firmware image can cause the bhyve process to crash, or possibly execute arbitrary code on the host as root.

powerdns Team reports:

CVE-2018-16855: An issue has been found in PowerDNS Recursor where a remote attacker sending a DNS query can trigger an out-of-bounds memory read while computing the hash of the query for a packet cache lookup, possibly leading to a crash. When the PowerDNS Recursor is run inside a supervisor like supervisord or systemd, a crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.

FasterXML jackson-databind before 2.8.11.1 and 2.9.x before 2.9.5 allows unauthenticated remote code execution because of an incomplete fix for the CVE-2017-7525 deserialization flaw. This is exploitable by sending maliciously crafted JSON input to the readValue method of the ObjectMapper, bypassing a blacklist that is ineffective if the c3p0 libraries are available in the classpath.

Albert Astals Cid reports:

messagelib is the library used by KMail to display emails.

messagelib by default displays emails as plain text, but gives the user an option to "Prefer HTML to plain text" in the settings and if that option is not enabled there is way to enable HTML display when an email contains HTML.

Some HTML emails can trick messagelib into opening a new browser window when displaying said email as HTML.

This happens even if the option to allow the HTML emails to access remote servers is disabled in KMail settings.

This means that the owners of the servers referred in the email can see in their access logs your IP address.

PowerDNS Team reports:

CVE-2018-10851: An issue has been found in PowerDNS Authoritative Server allowing an authorized user to cause a memory leak by inserting a specially crafted record in a zone under their control, then sending a DNS query for that record. The issue is due to the fact that some memory is allocated before the parsing and is not always properly released if the record is malformed. When the PowerDNS Authoritative Server is run inside the guardian (--guardian), or inside a supervisor like supervisord or systemd, an out-of-memory crash will lead to an automatic restart, limiting the impact to a somewhat degraded service.

CVE-2018-14626: An issue has been found in PowerDNS Authoritative Server allowing a remote user to craft a DNS query that will cause an answer without DNSSEC records to be inserted into the packet cache and be returned to clients asking for DNSSEC records, thus hiding the presence of DNSSEC signatures for a specific qname and qtype. For a DNSSEC-signed domain, this means that DNSSEC validating clients will consider the answer to be bogus until it expires from the packet cache, leading to a denial of service.

Albert Astals Cid reports:

Various KDE applications share a plugin system to create thumbnails of various file types for displaying in file managers, file dialogs, etc. kio-extras contains a thumbnailer plugin for HTML files.

The HTML thumbnailer was incorrectly accessing some content of remote URLs listed in HTML files. This meant that the owners of the servers referred in HTML files in your system could have seen in their access logs your IP address every time the thumbnailer tried to create the thumbnail.

The HTML thumbnailer has been removed in upcoming KDE Applications 18.12.0 because it was actually not creating thumbnails for files at all.

The OpenSSL project reports:

Microarchitecture timing vulnerability in ECC scalar multiplication. Severity: Low

OpenSSL ECC scalar multiplication, used in e.g. ECDSA and ECDH, has been shown to be vulnerable to a microarchitecture timing side channel attack. An attacker with sufficient access to mount local timing attacks during ECDSA signature generation could recover the private key.

NVD reports:

An issue was discovered in GNU patch through 2.7.6. There is a segmentation fault, associated with a NULL pointer dereference, leading to a denial of service in the intuit_diff_type function in pch.c, aka a "mangled rename" issue.

A double free exists in the another_hunk function in pch.c in GNU patch through 2.7.6.

GNU Patch version 2.7.6 contains an input validation vulnerability when processing patch files, specifically the EDITOR_PROGRAM invocation (using ed) can result in code execution. This attack appear to be exploitable via a patch file processed via the patch utility. This is similar to FreeBSD's CVE-2015-1418 however although they share a common ancestry the code bases have diverged over time.

The OpenSSL project reports:

Timing vulnerability in ECDSA signature generation (CVE-2018-0735): The OpenSSL ECDSA signature algorithm has been shown to be vulnerable to a timing side channel attack. An attacker could use variations in the signing algorithm to recover the private key (Low).

NGINX Team reports:

Two security issues were identified in nginx HTTP/2 implementation, which might cause excessive memory consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).

The issues affect nginx compiled with the ngx_http_v2_module (not compiled by default) if the "http2" option of the "listen" directive is used in a configuration file.

A security issue was identified in the ngx_http_mp4_module, which might allow an attacker to cause infinite loop in a worker process, cause a worker process crash, or might result in worker process memory isclosure by using a specially crafted mp4 file (CVE-2018-16845).

The issue only affects nginx if it is built with the ngx_http_mp4_module (the module is not built by default) and the "mp4" directive is used in the configuration file. Further, the attack is only possible if an attacker is able to trigger processing of a specially crafted mp4 file with the ngx_http_mp4_module.

Drupal Security Team reports:

curl security problems:

CVE-2018-16839: SASL password overflow via integer overflow

libcurl contains a buffer overrun in the SASL authentication code.

The internal function Curl_auth_create_plain_message fails to correctly verify that the passed in lengths for name and password aren't too long, then calculates a buffer size to allocate.

On systems with a 32 bit size_t, the math to calculate the buffer size triggers an integer overflow when the user name length exceeds 2GB (2^31 bytes). This integer overflow usually causes a very small buffer to actually get allocated instead of the intended very huge one, making the use of that buffer end up in a heap buffer overflow.

This bug is very similar to CVE-2017-14618.

It affects curl 7.33.0 to 7.61.1.

CVE-2018-16840: use-after-free in handle close

libcurl contains a heap use-after-free flaw in code related to closing an easy handle.

When closing and cleaning up an "easy" handle in the Curl_close() function, the library code first frees a struct (without nulling the pointer) and might then subsequently erroneously write to a struct field within that already freed struct.

It affects curl 7.59.0 to 7.61.1.

CVE-2018-16842: warning message out-of-buffer read

curl contains a heap out of buffer read vulnerability.

The command line tool has a generic function for displaying warning and informational messages to stderr for various situations. For example if an unknown command line argument is used, or passed to it in a "config" file.

This display function formats the output to wrap at 80 columns. The wrap logic is however flawed, so if a single word in the message is itself longer than 80 bytes the buffer arithmetic calculates the remainder wrong and will end up reading behind the end of the buffer. This could lead to information disclosure or crash.

This vulnerability could lead to a security issue if used in this or similar situations:

1. a server somewhere uses the curl command line to run something

2. if it fails, it shows stderr to the user

3. the server takes user input for parts of its command line input

4. user provides something overly long that triggers this crash

5. the stderr output may now contain user memory contents that wasn't meant to be available

It affects curl 7.14.1 to 7.61.1.

CVE-2018-16395: OpenSSL::X509::Name equality check does not work correctly

An instance of OpenSSL::X509::Name contains entities such as CN, C and so on. Some two instances of OpenSSL::X509::Name are equal only when all entities are exactly equal. However, there is a bug that the equality check is not correct if the value of an entity of the argument (right-hand side) starts with the value of the receiver (left-hand side). So, if a malicious X.509 certificate is passed to compare with an existing certificate, there is a possibility to be judged incorrectly that they are equal.

CVE-2018-16396: Tainted flags are not propagated in Array#pack and String#unpack with some directives

Array#pack method converts the receiver's contents into a string with specified format. If the receiver contains some tainted objects, the returned string also should be tainted. String#unpack method which converts the receiver into an array also should propagate its tainted flag to the objects contained in the returned array. But, with B, b, H and h directives, the tainted flags are not propagated. So, if a script processes unreliable inputs by Array#pack and/or String#unpack with these directives and checks the reliability with tainted flags, the check might be wrong.

libssh versions 0.6 and above have an authentication bypass vulnerability in the server code. By presenting the server an SSH2_MSG_USERAUTH_SUCCESS message in place of the SSH2_MSG_USERAUTH_REQUEST message which the server would expect to initiate authentication, the attacker could successfully authentciate without any credentials.

The Tox project blog reports:

A memory leak bug was discovered in Toxcore that can be triggered remotely to exhaust one?s system memory, resulting in a denial of service attack. The bug is present in the TCP Server module of Toxcore and therefore it affects mostly bootstrap nodes. Regular Tox clients generally have the TCP Server functionality disabled by default, leaving them unaffected.

Django release notes:

CVE-2018-16984: Password hash disclosure to "view only" admin users

If an admin user has the change permission to the user model, only part of the password hash is displayed in the change form. Admin users with the view (but not change) permission to the user model were displayed the entire hash. While it's typically infeasible to reverse a strong password hash, if your site uses weaker password hashing algorithms such as MD5 or SHA1, it could be a problem.
