Description

Created ImageMagick tracking bugs for this issue: Affects: fedora-all [bug 1378790] The POC actually causes an endless loop. We're probably missing some EOF checks in loops. Upstream seems to have tackled the loop problem in: https://github.com/ImageMagick/ImageMagick/commit/c1cf4802653970c050d175a6496fa1f11b7c089e Additionally, the patch for the integer overflow does not really work for me. The compiler optimizes the check into nothing. Even if that's changed, it still does not seem to work properly. Statement: Red Hat Product Security has rated this issue as having Moderate security impact. This issue is not currently planned to be addressed in future updates.
