PKCS12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS12 structure using a length taken directly fr...
