CVE-2024-26130
February 21, 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 version 42.0.4, the first version in which a "ValueError" is properly raised.
