When processing an RLE-compressed SGI image, the plugin allocates memory for a row table. The image header dimensions (ysize and zsize) are read as 16-bit unsigned integers. If a crafted file sets both dimensions to their maximum value (65535), the multiplication ysize * zsize overflows the standard 32-bit int boundary before being passed to calloc. This integer overflow issue results in undefined behavior, aborting the plugin and causing a denial of service."}],"affected":[{"vendor":"GNOME","product":"GIMP","packageName":"gimp","collectionURL":"https://gitlab.gnome.org/GNOME/gimp","defaultStatus":"affected"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gimp","defaultStatus":"unknown","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gimp","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gimp:2.8/gimp","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"gimp","defaultStatus":"affected","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-66757","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2507465","name":"RHBZ#2507465","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://gitlab.gnome.org/GNOME/gimp/-/work_items/16494"}],"datePublic":"2026-07-07T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-190","description":"Integer Overflow or Wraparound","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-190: Integer Overflow or Wraparound","workarounds":[{"lang":"en","value":"To mitigate this vulnerability, do not open SGI files from untrusted sources with GIMP."}],"timeline":[{"lang":"en","time":"2026-07-07T00:00:00.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-07-07T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Arjun Basnet (Securin) for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-07-31T15:19:36.468Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"references":[{"url":"https://gitlab.gnome.org/GNOME/gimp/-/work_items/16494","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-27T20:21:10.980868Z","id":"CVE-2026-66757","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-27T20:21:37.962Z"}}]}}
