Description Ganesh 2026-08-10 11:00:16 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.

A source-level audit of GIMP's file format plugins identified 2 vulnerabilities in default-install plugins (file-psd, file-paa). Both are triggerable by opening a crafted image file — no user interaction beyond "File > Open" is required. Each finding has been independently reproduced with a standalone PoC and confirmed via AddressSanitizer or arithmetic verification in a Docker environment (Fedora 41, gcc, zlib-devel).

This bug appears to have been reported against 'rawhide' during the Fedora Linux 45 development cycle.
Changing version to 45.
