OpenSSL project reports:

  1. Historically OpenSSL only ever generated DH parameters based on "safe" primes. More recently (in version 1.0.2) support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be "safe". Where an application is using DH configured with parameters based on primes that are not "safe" then an attacker could use this fact to find a peer's private DH exponent. This attack requires that the attacker complete multiple handshakes in which the peer uses the same private DH exponent. For example this could be used to discover a TLS server's private DH exponent if it's reusing the private DH exponent or it's using a static DH ciphersuite. OpenSSL provides the option SSL_OP_SINGLE_DH_USE for ephemeral DH (DHE) in TLS. It is not on by default. If the option is not set then the server reuses the same private DH exponent for the life of the server process and would be vulnerable to this attack. It is believed that many popular applications do set this option and would therefore not be at risk. (CVE-2016-0701)
  2. A malicious client can negotiate SSLv2 ciphers that have been disabled on the server and complete SSLv2 handshakes even if all SSLv2 ciphers have been disabled, provided that the SSLv2 protocol was not also disabled via SSL_OP_NO_SSLv2. (CVE-2015-3197)

03175e62-5494-11e4-9cc1-bc5ff4fb5e7bOpenSSL -- multiple vulnerabilities

The OpenSSL Project reports:

A flaw in the DTLS SRTP extension parsing code allows an attacker, who sends a carefully crafted handshake message, to cause OpenSSL to fail to free up to 64k of memory causing a memory leak. This could be exploited in a Denial Of Service attack. This issue affects OpenSSL 1.0.1 server implementations for both SSL/TLS and DTLS regardless of whether SRTP is used or configured. Implementations of OpenSSL that have been compiled with OPENSSL_NO_SRTP defined are not affected. [CVE-2014-3513].

When an OpenSSL SSL/TLS/DTLS server receives a session ticket the integrity of that ticket is first verified. In the event of a session ticket integrity check failing, OpenSSL will fail to free memory causing a memory leak. By sending a large number of invalid session tickets an attacker could exploit this issue in a Denial Of Service attack. [CVE-2014-3567].

OpenSSL has added support for TLS_FALLBACK_SCSV to allow applications to block the ability for a MITM attacker to force a protocol downgrade.

Some client applications (such as browsers) will reconnect using a downgraded protocol to work around interoperability bugs in older servers. This could be exploited by an active man-in-the-middle to downgrade connections to SSL 3.0 even if both sides of the connection support higher protocols. SSL 3.0 contains a number of weaknesses including POODLE [CVE-2014-3566].

When OpenSSL is configured with "no-ssl3" as a build option, servers could accept and complete a SSL 3.0 handshake, and clients could be configured to send them. [CVE-2014-3568].

The OpenSSL Project reports:

A flaw in OBJ_obj2txt may cause pretty printing functions such as X509_name_oneline, X509_name_print_ex et al. to leak some information from the stack. [CVE-2014-3508]

The issue affects OpenSSL clients and allows a malicious server to crash the client with a null pointer dereference (read) by specifying an SRP ciphersuite even though it was not properly negotiated with the client. [CVE-2014-5139]

If a multithreaded client connects to a malicious server using a resumed session and the server sends an ec point format extension it could write up to 255 bytes to freed memory. [CVE-2014-3509]

An attacker can force an error condition which causes openssl to crash whilst processing DTLS packets due to memory being freed twice. This can be exploited through a Denial of Service attack. [CVE-2014-3505]

An attacker can force openssl to consume large amounts of memory whilst processing DTLS handshake messages. This can be exploited through a Denial of Service attack. [CVE-2014-3506]

By sending carefully crafted DTLS packets an attacker could cause openssl to leak memory. This can be exploited through a Denial of Service attack. [CVE-2014-3507]

OpenSSL DTLS clients enabling anonymous (EC)DH ciphersuites are subject to a denial of service attack. A malicious server can crash the client with a null pointer dereference (read) by specifying an anonymous (EC)DH ciphersuite and sending carefully crafted handshake messages. [CVE-2014-3510]

A flaw in the OpenSSL SSL/TLS server code causes the server to negotiate TLS 1.0 instead of higher protocol versions when the ClientHello message is badly fragmented. This allows a man-in-the-middle attacker to force a downgrade to TLS 1.0 even if both the server and the client support a higher protocol version, by modifying the client's TLS records. [CVE-2014-3511]

A malicious client or server can send invalid SRP parameters and overrun an internal buffer. Only applications which are explicitly set up for SRP use are affected. [CVE-2014-3512]
