CVE-2017-17081
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.
Does this matter?
Lower severity and a low EPSS score (1.83%). Track it; it rarely justifies an emergency change on its own.
