+++ This bug was initially created as a clone of Bug #150677 +++
gifload in GIMP 2.0.5, 2.2.3, and possibly 2.2.4 allows remote attackers or
local users to cause a denial of service (application crash) via the image
descriptor (1) height or (2) width fields set to zero.
attachment 111813 [details] is a demo image to trigger this issue.
This issue should also affect FC2.
I've backported the patch from gimp CVS HEAD and built a package for FC3 which
should hit the mirrors shortly. Since this doesn't seem to be a real security
problem (plug-in crashes in an assertion, not negatively affecting the main
application) I won't fix this for FC2 due to its short remaining lifetime.
Crashing a client application on load of a malicious image is not a security
issue -- don't load the bad image. (agreed don't fix for FC2)
