CVE-2014-1549

Estado: ModificadaAlta (9.3)—

La función mozilla::dom::AudioBufferSourceNodeEngine::CopyFromInputBuffer en Mozilla Firefox anterior a 31.0 y Thunderbird anterior a 31.0 no asigna debidamente la memoria del buffer Web Audio, lo que permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (desbordamiento de buffer y caída de aplicación) a través de contenido de audio manipulado que se maneja indebidamente durante el uso del búfer de reproducción.
