A flaw was found in GIMP's file format plugins, including those for PSD and PAA files.

This could lead to unexpected application behavior or other potential security impacts without requiring further user interaction.

Description OSIDB Bzimport 2026-07-02 15:44:04 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).
