CVE-2015-5894

Description

The X.509 certificate-trust implementation in Apple OS X before 10.11 does not recognize that the kSecRevocationRequirePositiveResponse flag implies a revocation-checking requirement, which makes it easier for man-in-the-middle attackers to spoof endpoints by leveraging access to a revoked certificate.
