CVE-2017-9990
Stack-based buffer overflow in the color_string_to_rgba function in libavcodec/xpmdec.c in FFmpeg 3.3 before 3.3.1 allows remote attackers to cause a denial of service (application crash) or possibly have unspecified other impact via a crafted file.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.57%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
