A stack buffer overflow vulnerability in the TIM image loader's 4BPP decoding path allows a local user to cause a Denial of Service (DoS). By opening a specially crafted TIM image file, the application crashes due to an unconditional overflow when writing to a variable-length array.\n\n## Affected\n\n- `gimp (all versions)`\n- `gimp (all versions)`\n- `gimp:2.8/gimp (all versions)`\n- `gimp (all versions)`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n### Workarounds\n\nTo mitigate this issue, users should avoid opening untrusted TIM image files with GIMP. As a general security practice, users should exercise caution when handling files from unknown or suspicious sources.","depth":"sunlit","depthScore":28,"depthScoreParts":{"impact":27.5,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
