Description Vladimir Vasilev 2026-09-23 07:42:58 UTC 
Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

ImageMagick before 7.1.2-31 and before 6.9.13-56 contains a NULL pointer dereference in the PNM coder. When the coder reaches a memory (resource) limit at a specific point during processing, the failed allocation is not handled and a NULL pointer is dereferenced, which can lead to a denial of service (application crash) when processing a specially crafted or sufficiently large PNM image.
Comment 1 Luya Tshimbalanga 2026-10-15 05:14:52 UTC 
The reported vulnerability was fixed upstream in ImageMagick 7.1.2-32 or an earlier release. Fedora 43 stable provides ImageMagick-7.1.2.32-1.fc43, which includes the fix.

Closing this Fedora 43 tracker as CURRENTRELEASE.
