CVE-2026-78322 (GCVE-0-2026-78322)

Vulnerability from cvelistv5 – Published: 2026-08-25 07:21 – Updated: 2026-08-25 07:21

Title

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

Summary

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.

Severity

6.5 (Medium)
