A fix is available — apply it.

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.
