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.

Affected products

• Canonical Ubuntu Linux: 12.04
• FFmpeg: through 2.4.1; 0.3, 0.3.1, 0.3.2, 0.3.3, 0.3.4, 0.4.0 (+98)
