CVE-2014-8542

Estado: ModificadaAlta (7.5)—

libavcodec/utils.c en FFmpeg anterior a 2.4.2 omite cierto identificador de codec durante el forzamiento de la alineación, lo que permite a atacantes remotos causar una denegación de servicio (acceso fuera de rango) o posiblemente tener otro impacto no especificado a través de datos JV manipulados.
