Description Siddharth Sharma 2018-05-24 01:27:24 EDT 
A flaw was found in glusterfs which can lead to privilege escalation on 
gluster server nodes.

It was found that any gluster client authenticated via TLS could use
gluster cli with --remote-host command to add itself to gluster trusted 
pool and perform all gluster operations like peer probe itself or other 
machines, start, stop, delete volumes etc.
