Descriptions

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.

La implementación del certificado de confianza X.509 en Apple OS X en versiones anteriores a 10.11 no reconoce que el indicador kSecRevocationRequirePositiveResponse implica un requerimiento de control de revocación, lo que hace más fácil para atacantes man-in-the-middle falsificar terminales mediante el aprovechamiento de acceso a un certificado revocado.

OS X El Capitan 10.11 is now available and addresses close to 100 vulnerabilities that may exist in prior releases.
