21 Feb 2024 — 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 ver... • https://github.com/pyca/cryptography/commit/97d231672763cdb5959a3b191e692a362f1b9e55 • CWE-476: NULL Pointer Dereference •
