{"id":"CVE-2026-82343","state":"PUBLISHED","title":"Gimp: heap out-of-bounds read and stack out-of-bounds access in psd loader from channel-count handling","description":"A flaw was found in the file-psd plugin in GIMP. When processing a specially crafted PSD image file, the plugin does not properly validate the channel-count parameter. This incorrect validation leads to improper memory bounds checking, resulting in both a heap out-of-bounds read and a stack out-of-bounds access. This issue can result in an application crash, leading to a denial of service or a limited information disclosure of memory contents.","publishedAt":"2026-08-28T16:26:13.284Z","updatedAt":"2026-09-01T14:59:39.177Z","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":"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-2026-82343","https://bugzilla.redhat.com/show_bug.cgi?id=2525644","https://gitlab.gnome.org/GNOME/gimp/-/work_items/16587"],"weaknesses":["CWE-120"],"ingestedAt":"2026-10-29T20:13:15.269Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/82xxx/CVE-2026-82343.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-82343","state":"PUBLISHED","datePublished":"2026-08-28T16:26:13.284Z","dateUpdated":"2026-09-01T14:59:39.177Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-08-28T16:11:58.606Z"},"containers":{"cna":{"title":"Gimp: heap out-of-bounds read and stack out-of-bounds access in psd loader from channel-count handling","descriptions":[{"lang":"en","value":"A flaw was found in the file-psd plugin in GIMP.
