1d56cfc5-3970-11eb-929d-d4c9ef517024 | OpenSSL -- NULL pointer de-reference
The OpenSSL project reports:
EDIPARTYNAME NULL pointer de-reference (High)
The X.509 GeneralName type is a generic type for representing
different types of names. One of those name types is known as
EDIPartyName. OpenSSL provides a function GENERAL_NAME_cmp which
compares different instances of a GENERAL_NAME to see if they
are equal or not. This function behaves incorrectly when both
GENERAL_NAMEs contain an EDIPARTYNAME. A NULL pointer
dereference and a crash may occur leading to a possible denial
of service attack.

648a432c-a71f-11ed-86e9-d4c9ef517024 | OpenSSL -- Multiple vulnerabilities
The OpenSSL project reports:
X.400 address type confusion in X.509 GeneralName (CVE-2023-0286) (High):
There is a type confusion vulnerability relating to X.400 address processing
inside an X.509 GeneralName. X.400 addresses were parsed as an ASN1_STRING but
the public structure definition for GENERAL_NAME incorrectly specified the type
of the x400Address field as ASN1_TYPE. This field is subsequently interpreted by
the OpenSSL function GENERAL_NAME_cmp as an ASN1_TYPE rather than an
ASN1_STRING.
Timing Oracle in RSA Decryption (CVE-2022-4304) (Moderate):
A timing based side channel exists in the OpenSSL RSA Decryption implementation
which could be sufficient to recover a plaintext across a network in a
Bleichenbacher style attack. To achieve a successful decryption an attacker
would have to be able to send a very large number of trial messages for
decryption. The vulnerability affects all RSA padding modes: PKCS#1 v1.5,
RSA-OEAP and RSASVE.
X.509 Name Constraints Read Buffer Overflow (CVE-2022-4203) (Moderate):
A read buffer overrun can be triggered in X.509 certificate verification,
specifically in name constraint checking. Note that this occurs
after certificate chain signature verification and requires either a
CA to have signed the malicious certificate or for the application to
continue certificate verification despite failure to construct a path
to a trusted issuer.
Use-after-free following BIO_new_NDEF (CVE-2023-0215) (Moderate):
The public API function BIO_new_NDEF is a helper function used for streaming
ASN.1 data via a BIO. It is primarily used internally to OpenSSL to support the
SMIME, CMS and PKCS7 streaming capabilities, but may also be called directly by
end user applications.
Double free after calling PEM_read_bio_ex (CVE-2022-4450) (Moderate):
The function PEM_read_bio_ex() reads a PEM file from a BIO and parses and
decodes the "name" (e.g. "CERTIFICATE"), any header data and the payload data.
If the function succeeds then the "name_out", "header" and "data" arguments are
populated with pointers to buffers containing the relevant decoded data. The
caller is responsible for freeing those buffers. It is possible to construct a
PEM file that results in 0 bytes of payload data. In this case PEM_read_bio_ex()
will return a failure code but will populate the header argument with a pointer
to a buffer that has already been freed. If the caller also frees this buffer
then a double free will occur. This will most likely lead to a crash. This
could be exploited by an attacker who has the ability to supply malicious PEM
files for parsing to achieve a denial of service attack.
Invalid pointer dereference in d2i_PKCS7 functions (CVE-2023-0216) (Moderate):
An invalid pointer dereference on read can be triggered when an
application tries to load malformed PKCS7 data with the
d2i_PKCS7(), d2i_PKCS7_bio() or d2i_PKCS7_fp() functions.
NULL dereference validating DSA public key (CVE-2023-0217) (Moderate):
An invalid pointer dereference on read can be triggered when an
application tries to check a malformed DSA public key by the
EVP_PKEY_public_check() function. This will most likely lead
to an application crash. This function can be called on public
keys supplied from untrusted sources which could allow an attacker
to cause a denial of service attack.
NULL dereference during PKCS7 data verification (CVE-2023-0401) (Moderate):
A NULL pointer can be dereferenced when signatures are being
verified on PKCS7 signed or signedAndEnveloped data. In case the hash
algorithm used for the signature is known to the OpenSSL library but
the implementation of the hash algorithm is not available the digest
initialization will fail. There is a missing check for the return
value from the initialization function which later leads to invalid
usage of the digest API most likely leading to a crash.

The OpenSSL project reports:
Null pointer deref in X509_issuer_and_serial_hash()
CVE-2021-23841 (Moderate) The OpenSSL public API function
X509_issuer_and_serial_hash() attempts to create a unique hash
value based on the issuer and serial number data contained within
an X509 certificate. However it fails to correctly handle any errors
that may occur while parsing the issuer field (which might occur if
the issuer field is maliciously constructed). This may subsequently
result in a NULL pointer deref and a crash leading to a potential
denial of service attack.
Integer overflow in CipherUpdate CVE-2021-23840 (Low)
Calls to EVP_CipherUpdate, EVP_EncryptUpdate and EVP_DecryptUpdate

integer on the platform. In such cases the return value from the
function call will be 1 (indicating success), but the output length
value will be negative. This could cause applications to behave
incorrectly or crash.

ea05c456-a4fd-11ec-90de-1c697aa5a594 | OpenSSL -- Infinite loop in BN_mod_sqrt parsing certificates
The OpenSSL project reports:
Infinite loop in BN_mod_sqrt() reachable when parsing certificates
(High)
The BN_mod_sqrt() function, which computes a modular square root,
contains a bug that can cause it to loop forever for non-prime
moduli.
Internally this function is used when parsing certificates that
contain elliptic curve public keys in compressed form or explicit
elliptic curve parameters with a base point encoded in compressed
form.
It is possible to trigger the infinite loop by crafting a
certificate that has invalid explicit curve parameters.
Since certificate parsing happens prior to verification of the
certificate signature, any process that parses an externally
supplied certificate may thus be subject to a denial of service
attack. The infinite loop can also be reached when parsing crafted
private keys as they can contain explicit elliptic curve
parameters.
Thus vulnerable situations include:
- TLS clients consuming server certificates
- TLS servers consuming client certificates
- Hosting providers taking certificates or private keys from
customers
- Certificate authorities parsing certification requests from
subscribers
- Anything else which parses ASN.1 elliptic curve parameters
Also any other applications that use the BN_mod_sqrt() where the
attacker can control the parameter values are vulnerable to this DoS
issue.

Problem Description:
Server or client applications that call the SSL_check_chain()
function during or after a TLS 1.3 handshake may crash due to a NULL
pointer dereference as a result of incorrect handling of the
"signature_algorithms_cert" TLS extension. The crash occurs if an
invalid or unrecognized signature algorithm is received from the
peer.
Impact:
A malicious peer could exploit the NULL pointer dereference crash,
causing a denial of service attack.

1aaaa5c6-804d-11ec-8be6-d4c9ef517024 | OpenSSL -- BN_mod_exp incorrect results on MIPS
The OpenSSL project reports:
BN_mod_exp may produce incorrect results on MIPS (Moderate)
There is a carry propagation bug in the MIPS32 and MIPS64 squaring
procedure. Many EC algorithms are affected, including some of the
TLS 1.3 default curves. Impact was not analyzed in detail, because the
pre-requisites for attack are considered unlikely and include reusing
private keys. Analysis suggests that attacks against RSA and DSA as a
result of this defect would be very difficult to perform and are not
believed likely. Attacks against DH are considered just feasible
(although very difficult) because most of the work necessary to deduce
information about a private key may be performed offline. The amount
of resources required for such an attack would be significant.
However, for an attack on TLS to be meaningful, the server would have
to share the DH private key among multiple clients, which is no longer
an option since CVE-2016-0701.

(Moderate)
The c_rehash script does not properly sanitise shell
metacharacters to prevent command injection. This script is distributed
by some operating systems in a manner where it is automatically

- OCSP_basic_verify may incorrectly verify the response signing

The function
`OCSP_basic_verify` verifies the signer certificate on an OCSP response.
