Sorry, looking back at the issue I think I mixed things up - It doesn't
help that the issues referenced in the commit messages have been deleted
(or hidden?) from their bugtracker. Bug #114 affected gifclrmp, bug #113
does indeed affect the library itself (CVE-2018-11490) and #119
(CVE-2019-15133) as well.

So a small patch adding the fixes to our current version would be the
nicest. Notice that the source files have been moved (and
deleted/restored) in upstream git, so the paths need a bit of tweaking.
