Echo: acl: security update to 2.4.0-1

high Tenable Self-Hosted Container Security Plugin ID 460371

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - acl before version 2.4.0 contains a symlink traversal vulnerability in the libacl pathname-based functions
 acl_get_file(), acl_set_file(), acl_extended_file(), and acl_delete_def_file() that allows local attackers
 to escalate privileges by replacing any pathname component with a symbolic link. Attackers who control any
 component of a pathname processed by a privileged caller can redirect ACL read or write operations to
 arbitrary files or directories, enabling unauthorized manipulation of access control lists and local
 privilege escalation. (CVE-2026-54369)

Solution

Update the acl library and its related packages to version 2.4.0-1 or later.
