CVE-2025-6035

Code execution via unchecked Despeckle buffer sizing

Published Jun 13, 2025 · Updated Jun 30, 2026

Integer overflow in GIMP's Despeckle plug-in before 3.0.4 allows local users to execute code by processing a very large image. The plug-in multiplies image width, height, and bytes per pixel without overflow checks, allocates an undersized heap buffer, and writes beyond it. Exploitation requires user interaction to run Despeckle on attacker-controlled image dimensions and can corrupt the process heap, crash GIMP, or execute code with the user's privileges.
