Description Josh Bressers 2005-10-27 12:49:29 EDT

These issues were reported by Ludwig Nussel of Suse.

When gdk-pixbuf processes a bad XPM file, it fails to verify that width * height
* colors doesn't cause an integer overflow.

Additionally gdk-pixbuf will enter an infinite loop if the number of colors
provided is very large, but not large enough to cause an integer overflow.

Comment 1 Josh Bressers 2005-10-27 12:50:10 EDT

These issues should also affect RHEL2.1 and RHEL3.
