Issue summary: Applications performing certificate name checks (e.g., TLS
clients checking server certificates) may attempt to read an invalid memory
address resulting in abnormal termination of the application process.
Impact summary: Abnormal termination of an application can a cause a denial of
service.
Applications performing certificate name checks (e.g., TLS clients checking
server certificates) may attempt to read an invalid memory address when
comparing the expected name with an `otherName` subject alternative name of an
X.509 certificate. This may result in an exception that terminates the
application program.
Note that basic certificate chain validation (signatures, dates, ...) is not
affected, the denial of service can occur only when the application also
specifies an expected DNS name, Email address or IP address.
TLS servers rarely solicit client certificates, and even when they do, they
generally don't perform a name check against a reference identifier (expected
identity), but rather extract the presented identity after checking the
certificate chain. So TLS servers are generally not affected and the severity
of the issue is Moderate.
The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

CVE-2024-26130
### Vulnerable Library - cryptography-41.0.7-cp37-abi3-manylinux_2_28_x86_64.whl
cryptography is a package which provides cryptographic recipes and primitives to Python developers.
cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Starting in version 38.0.0 and prior to version 42.0.4, if `pkcs12.serialize_key_and_certificates` is called with both a certificate whose public key did not match the provided private key and an `encryption_algorithm` with `hmac_hash` set (via `PrivateFormat.PKCS12.encryption_builder().hmac_hash(...)`, then a NULL pointer dereference would occur, crashing the Python process. This has been resolved in version 42.0.4, the first version in which a `ValueError` is properly raised.

CVE-2023-50782
### Vulnerable Library - cryptography-41.0.7-cp37-abi3-manylinux_2_28_x86_64.whl
cryptography is a package which provides cryptographic recipes and primitives to Python developers.
A flaw was found in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which may lead to exposure of confidential or sensitive data.
