CWE ID 476


CVE-2024-26130 is a vulnerability in the cryptography package for Python. It affects versions 38.0.0 to 42.0.4 of the package. The vulnerability occurs when the function pkcs12.serialize_key_and_certificates is called with a certificate whose public key does not match the provided private key, and an encryption algorithm with hmac_hash set. This results in a NULL pointer dereference, causing the Python process to crash. The issue has been resolved in version 42.0.4, where a ValueError is properly raised instead of crashing the process. This vulnerability has a high severity rating and can be exploited remotely over a network without requiring any user interaction or privileges.
