CVE-2014-8838

Estado: ModificadaMedia (4.3)—

El componente de seguridad en Apple OS X anterior a 10.10.2 no procesa correctamente la información en caché sobre los certificados de aplicaciones, lo que permite a atacantes evadir el mecanismo de protección Gatekeeper mediante el aprovechamiento del acceso a un certificado de identificación Developer revocado a la espera de firmarse una aplicación manipulada.
