{"id":"CVE-2026-78475","state":"PUBLISHED","title":"Gimp: unbounded stack vla and 21-byte stack over-read in pix (esm) loader","description":"A flaw was found in the file-pix (ESM) plugin in GIMP. When processing a specially crafted PIX image file, the plugin allocates a Variable-Length Array (VLA) on the stack without proper bounds checking, causing an unbounded stack allocation followed by a 21-byte stack over-read. This can result in a denial of service due to stack exhaustion and a limited information disclosure of stack memory contents into an intermediate file.","publishedAt":"2026-08-24T17:20:48.050Z","updatedAt":"2026-08-25T13:46:20.344Z","severity":{"score":6.1,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","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":"unaffected","versions":[{"version":"3.0.0","status":"affected","lessThan":"*","versionType":"semver"}],"collectionURL":"https://gitlab.gnome.org/GNOME/gimp"},{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","packageName":"gimp","defaultStatus":"unaffected","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":"unaffected","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":"unaffected","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-2026-78475","https://bugzilla.redhat.com/show_bug.cgi?id=2522072","https://gitlab.gnome.org/GNOME/gimp/-/work_items/16580"],"weaknesses":["CWE-125"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/78xxx/CVE-2026-78475.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-78475","state":"PUBLISHED","datePublished":"2026-08-24T17:20:48.050Z","dateUpdated":"2026-08-25T13:46:20.344Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-08-24T16:51:43.273Z"},"containers":{"cna":{"title":"Gimp: unbounded stack vla and 21-byte stack over-read in pix (esm) loader","descriptions":[{"lang":"en","value":"A flaw was found in the file-pix (ESM) plugin in GIMP.
