Arbitrary code execution or crash via GIF overflow
Published Apr 15, 2026 · Updated Apr 15, 2026
Buffer overflow in GIMP on Red Hat Enterprise Linux 6 and 8 allows local users to execute code or crash GIMP via a crafted GIF file. The GIF loader's ReadJeffsImage function copies attacker-controlled image data beyond its allocated buffer while parsing the file. Exploitation requires user interaction to open the malicious file; RHEL 7 and 9 omit the vulnerable code.
