giflib v5.2.1 was discovered to contain a segmentation fault via the component getarg.c. https://gist.github.com/huanglei3/ec9090096aa92445cf0a8baa8e929084 https://sourceforge.net/p/giflib/bugs/166/
Looks like this only affects the command line utilities and not the library itself.
Created giflib tracking bugs for this issue: Affects: fedora-all [bug 2238790]
