Vulnerability Name:

CVE-2013-3672 (CCN-84915)

Assigned:

2013-06-09

Published:

Updated:

2015-10-28

Summary:

The mm_decode_inter function in mmvideo.c in libavcodec in FFmpeg before 1.2.1 does not validate the relationship between a horizontal coordinate and a width value, which allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) via crafted American Laser Games (ALG) MM Video data.
