CVE-2014-8541 Information

Description

libavcodec/mjpegdec.c in FFmpeg before 2.4.2 considers only dimension differences and not bits-per-pixel differences when determining whether an image size has changed which allows remote attackers to cause a denial of service (out-of-bounds access) or possibly have unspecified other impact via crafted MJPEG data.
