## Description

glusterfs is vulnerable to privilege escalation on gluster server nodes. An
authenticated gluster client via TLS could use gluster cli with
--remote-host command to add it self to trusted storage pool and perform
privileged gluster operations like adding other machines to trusted storage
pool, start, stop, and delete volumes.

### From the Ubuntu Security Team

It was discovered that GlusterFS incorrectly handled user permissions. An
authenticated attacker could possibly use this to add himself to trusted
storage pool and performing privileged operations on volumes.
