{"id":"CVE-2026-78322","state":"PUBLISHED","title":"File-roller: file-roller: stack buffer overflow in parse_progress_line for 7z and rar handlers","description":"A flaw was found in file-roller. When opening or extracting a malicious 7z or RAR archive containing a file entry with an excessively long path, file-roller's progress-line parsing copies the path into a fixed-size stack buffer using an unbounded string copy. This can trigger a stack buffer overflow and cause file-roller to terminate, resulting in a denial of service. To exploit this flaw, a victim must open or extract the crafted archive using file-roller.","publishedAt":"2026-08-25T07:21:38.573Z","updatedAt":"2026-08-27T14:59:54.395Z","severity":{"score":6.5,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","source":"redhat"},"assigner":"redhat","products":["Red Hat Red Hat Enterprise Linux 6","Red Hat Red Hat Enterprise Linux 7","Red Hat Red Hat Enterprise Linux 8"],"affected":[{"vendor":"Red Hat","product":"Red Hat Enterprise Linux 6","packageName":"file-roller","defaultStatus":"affected","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":"file-roller","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":"file-roller","defaultStatus":"affected","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","cpes":["cpe:/o:redhat:enterprise_linux:8"]}],"references":["https://access.redhat.com/security/cve/CVE-2026-78322","https://bugzilla.redhat.com/show_bug.cgi?id=2521767","https://gitlab.gnome.org/GNOME/file-roller/-/commit/ffb76dc866342cef6a4914873faaa880d14d5aa4","https://gitlab.gnome.org/GNOME/file-roller/-/issues/327"],"weaknesses":["CWE-120"],"ingestedAt":"2026-10-29T20:13:07.220Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/78xxx/CVE-2026-78322.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-78322","state":"PUBLISHED","datePublished":"2026-08-25T07:21:38.573Z","dateUpdated":"2026-08-27T14:59:54.395Z","assignerShortName":"redhat","assignerOrgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","dateReserved":"2026-08-24T08:53:42.508Z"},"containers":{"cna":{"title":"File-roller: file-roller: stack buffer overflow in parse_progress_line for 7z and rar handlers","descriptions":[{"lang":"en","value":"A flaw was found in file-roller.
