Out-of-bounds Access Vulnerability in FFmpeg's MJPEG Decoder

CVE-2014-8541 · HIGH Severity

AV:N/AC:L/AU:N/C:P/I:P/A:P

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.
