cryptography NULL pointer dereference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override
If pkcs12.serialize_key_and_certificates is called with both:
- A certificate whose public key did not match the provided private key
- An
encryption_algorithmwithhmac_hashset (viaPrivateFormat.PKCS12.encryption_builder().hmac_hash(...)
Then a NULL pointer dereference would occur, crashing the Python process.
This has been resolved, and now a ValueError is properly raised.

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.
