EulerOS 2.0 SP12 : attr (EulerOS-SA-2026-3248)

high Nessus Plugin ID 343699

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the versions of the attr packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

 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)

Tenable has extracted the preceding description block directly from the EulerOS attr 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

Update the affected attr packages.
