JSON

A flaw was discovered in python-cryptography. A NULL pointer dereference can be triggered when a PKCS#12 key and certificate do not match. Specifically, if the pkcs12.serialize_key_and_certificates function is called with a non-matching certificate and private key and an encryption algorithm with hmac_hash set, the Python process may crash, leading to a denial of service.

Mitigation

Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
