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."}], "lastModified": "2026-08-28T21:17:10.720", "sourceIdentifier": "secalert@redhat.com"}
