CVE-2017-17081Date: (C)2017-12-06   (M)2023-12-22


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.
