CVE-2019-15133
In GIFLIB before 2019-02-16, a malformed GIF file triggers a divide-by-zero exception in the decoder function DGifSlurp in dgif_lib.c if the height field of the ImageSize data structure is equal to zero.
Does this matter?
Lower severity and a low EPSS score (1.54%). Track it; it rarely justifies an emergency change on its own.
