Doc Type: Bug Fix
Doc Text:
A memory corruption flaw was found in the way Qt handled certain GIF image files. If a user loaded a specially crafted GIF image file with an application linked against Qt, it could cause the application to crash or, possibly, execute arbitrary code with the privileges of the user running the application.

Comment 4 Kevin Kofler 2015-04-21 23:39:14 UTC 
Qt 3 appears to be VULNERABLE to this issue. (The offending code can be found in src/kernel/qasyncimageio.cpp.) I am backporting the fix from Qt 4 to the Fedora qt3 package.

Qt 4 and Qt 5 are also vulnerable, and Fedora updates correcting this vulnerability have been issued.
