CentOS 9 : attr-2.6.0-2.el9

high Nessus Plugin ID 326776

Synopsis

The remote CentOS host is missing a security update for attr.

Description

The remote CentOS Linux 9 host has packages installed that are affected by a vulnerability as referenced in the attr-2.6.0-2.el9 build changelog.

- attr before version 2.6.0 contains a symlink traversal vulnerability in the getfattr and setfattr utilities that allows local attackers to escalate privileges by replacing a pathname component with a symbolic link during directory hierarchy traversal. Attackers who control a pathname component can redirect getfattr and setfattr operations to arbitrary files by substituting a symlink, leading to local privilege escalation when getfattr or setfattr is invoked by a privileged process over an attacker- controlled path. (CVE-2026-54371)

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

Solution

Update the CentOS 9 Stream attr package.
