CVE-2015-1872

Estado: ModificadaMedia (6.8)—

Vulnerabilidad en la función ff_mjpeg_decode_sof en libavcodec/mjpegdec.c en FFmpeg en versiones anteriores a 2.5.4, no valida el número de componentes en un segmento de JPEG-LS Start Of Frame, que permite a atacantes remotos provocar una denegación de servicio (acceso a array fuera de límites) o, posiblemente, tener otro impacto no especificado a través de datos Motion JPEG manipulados.
