When processing a specially crafted XWD image file, the plugin validates the image width and bytes-per-line parameters independently rather than ensuring their combined values are consistent with the allocated buffer size. This incorrect validation leads to improper bounds checking, causing a heap out-of-bounds read. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of heap memory contents into the produced image.\n\n## Affected\n\n- `gimp (all versions)`\n- `gimp`\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 vulnerability, do not open XWD files from untrusted sources with GIMP.","depth":"twilight","depthScore":36,"depthScoreParts":{"impact":24.2,"likelihood":0,"exploitation":12,"ransomware":0},"changes":[]}
