Description OSIDB Bzimport 2026-07-02 15:42:36 UTC 
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).
