CVE-2015-0805

Estado: ModificadaAlta (7.5)—

La implementación Off Main Thread Compositing (OMTC) en Mozilla Firefox anterior a 37.0 hace una llamada memset incorrecta durante la interacción con la función mozilla::layers::BufferTextureClient::AllocateForSurface, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria y caída de aplicación) a través de vectores que provocan la renderización de contenidos de gráficos en 2D.
