{"id":"CVE-2026-80101","state":"PUBLISHED","title":"Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation","description":"A flaw was found in the file-xwd plugin in GIMP. 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.","publishedAt":"2026-08-25T20:36:47.429Z","updatedAt":"2026-09-02T17:20:23.328Z","severity":{"score":4.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:L","source":"redhat"},"assigner":"redhat","products":["GNOME GIMP","Red Hat Red Hat Enterprise Linux 6","Red Hat Red Hat Enterprise Linux 7","Red Hat Red Hat Enterprise Linux 8","Red Hat Red Hat Enterprise Linux 9"],"affected":[{"vendor":"GNOME","product":"GIMP","packageName":"gimp","defaultStatus":"affected","collectionURL":"https://gitlab.gnome.org/GNOME/gimp"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","packageName":"gimp","defaultStatus":"unknown","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:6"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 7","packageName":"gimp","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:7"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 8","packageName":"gimp:2.8/gimp","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:8"]},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 9","packageName":"gimp","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:9"]}],"references":["https://access.redhat.com/security/cve/CVE-2026-80101","https://bugzilla.redhat.com/show_bug.cgi?id=2523738","https://gitlab.gnome.org/GNOME/gimp/-/work_items/16583"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/80xxx/CVE-2026-80101.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-80101","state":"PUBLISHED","datePublished":"2026-08-25T20:36:47.429Z","dateUpdated":"2026-09-02T17:20:23.328Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-08-25T19:27:39.490Z"},"containers":{"cna":{"title":"Gimp: multiple heap out-of-bounds reads in xwd loader from unrelated width and bytes-per-line validation","descriptions":[{"lang":"en","value":"A flaw was found in the file-xwd plugin in GIMP.
