CVE-2015-1255

Estado: ModificadaMedia (6.8)—

Vulnerabilidad de uso después de liberación en content/renderer/media/webaudio_capturer_source.cc en la implementación WebAudio en Google Chrome anterior a 43.0.2357.65 permite a atacantes remotos causar una denegación de servicio (corrupción de la memoria dinámica) o posiblemente tener otro impacto no especificado mediante el aprovechamiento del manejo incorrecto de una acción de parar para una pista de audio.
