Comment 13 Siddharth Sharma 2018-09-04 13:44:54 UTC 
Mitigation:

SELinux mitigates this issue on Red Hat Gluster Storage 3. SELinux should be in enforcing mode only as permissive mode does not block attacks.
Comment 14 Doran Moppert 2018-09-06 04:43:40 UTC 
Statement:

This issue did not affect Red Hat Enterprise Linux 6 and 7 as the flaw is present in glusterfs-server, which is not shipped there.

This flaw affects glusterfs versions included in Red Hat Virtualization 4 Hypervisor. However, in recommended configurations, the vulnerability is only exposed to hypervisor administrators and can not be exploited from virtual machines or other hosts on the network.
Comment 15 errata-xmlrpc 2018-11-05 14:56:51 UTC 
This issue has been addressed in the following products:

  Red Hat Virtualization 4 for Red Hat Enterprise Linux 7
