CVE-2017-17081 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:18.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ffmpeg package and not the ffmpeg package as distributed by Ubuntu.
The gmc_mmx function in libavcodec/x86/mpegvideodsp.c in FFmpeg 2.3 and 3.4 does not properly validate widths and heights, which allows remote attackers to cause a denial of service (integer signedness error and out-of-array read) via a crafted MPEG file.
