CVE-2018-5160

Estado: ModificadaAlta (7.5)—

WebRTC puede utilizar un búfer de píxeles "WrappedI420Buffer", pero el objeto owning image puede liberarse mientras está en uso. Esto puede provocar que el codificador WebRTC utilice memoria no inicializada, lo que puede provocar un cierre inesperado potencialmente explotable. Esta vulnerabilidad afecta a las versiones anteriores a la 60 de Firefox.
