gd denial of service A flaw was found in the way gd loads certain malformed GIF images. If a user loads a broken GIF image it is possible to cause gd to enter an infinite loop. There is more information in the bugtraq mail: http://www.securityfocus.com/archive/1/436132 This issue also affects FC4
Created attachment 130771 [details] Testcase based on the C in the bugtraq mail. This testcase doesn't seem to crash when loading a gif image via a file stream, but does when the data is loaded via a pointer.
