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.

The remote Oracle Linux 8 host has packages installed that are affected by a vulnerability as referenced in the ELSA-2026-56133 advisory.

    - rebase to 2.6.0 to fix the following CVEs:
