CVE-2017-7962
The iwgif_read_image function in imagew-gif.c in libimageworsener.a in ImageWorsener 1.3.0 allows remote attackers to cause a denial of service (divide-by-zero error and application crash) via a crafted file.
Does this matter?
Lower severity and a low EPSS score (1.21%). Track it; it rarely justifies an emergency change on its own.
