Buffer overflow in FFmpeg - CVE-2014-8541
Published: December 3, 2016 / Updated: June 8, 2025
FFmpeg
Detailed vulnerability description
The vulnerability allows a remote non-authenticated attacker to read and manipulate data.
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.
