Could you please attach a sample failing gif? Created attachment 159992 [details]
Failing gif file
Here you go.
Is this ever get fixed? This issue drives me crazy. I found this patch on the internet: http://users.own- hero.net/~decoder/fuzzyocr/giftext-segfault.patch can someone can take a look if it could be included into the RedHat's RPM? Still there in 5.1. Is anybody responsible for this bug is still here? Created attachment 338515 [details] Upstream patch (extracted change from upstream 4.1.6) (In reply to comment #4) > I found this patch on the internet: http://users.own- > hero.net/~decoder/fuzzyocr/giftext-segfault.patch can someone can take a look > if it could be included into the RedHat's RPM? Should be this, which is a one-liner diff between 4.1.3 and 4.1.6. Fixes not exploitable NULL pointer dereference flaw.
