CVE-2026-78322: Red Hat Enterprise Linux 6

Medium severity, CVSS 6.5. EPSS: 0.5% chance of exploitation in the next 30 days.

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.
