Summary

file-roller security update

Details

File Roller is an archive manager that you can create and modify archives; view the content of an archive;view and modify a file contained in the archive; extract files from the archive.

Security Fix(es):

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.(CVE-2026-78322)

Severity

6.5 (Medium)
