Hi,

The following vulnerability was published for python-cryptography.

CVE-2024-26130[0]:
| 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.


If you fix the vulnerability please also make sure to include the
