CVE-2015-6997

Estado: ModificadaMedia (4.3)—

La implementación del certificado de confianza X.509 en Apple iOS en versiones anteriores a 9.1 no reconoce que el indicador kSecRevocationRequirePositiveResponse implica un requerimiento de verificación de revocación, lo que hace más fácil para atacantes man-in-the-middle falsificar terminales aprovechando el acceso a un certificado revocado.
