Amazon Linux 2 : file-roller (ALAS-2026-4050)

medium Nessus Plugin ID 374363

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of file-roller installed on the remote host is prior to 3.28.1-2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-4050 advisory.

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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update file-roller' or or 'yum update --advisory ALAS2-2026-4050' to update your system.
