CVE-2026-78322

File-roller: file-roller: stack buffer overflow in parse_progress_line for 7z and rar handlers

Published Aug 25, 2026 CVSS 3.1 · 6.5 Medium EPSS < 1% KEV · Not listed
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.

Remediation

Vendor Workaround

Avoid opening or extracting untrusted 7z or RAR archives with file-roller until an updated package is installed.
