Description Adam Mariš 2017-09-07 09:25:29 UTC 
When deploying overcloud by Director, it was found that ceph client keyring is created as world-readable potentially allowing local attackers to read or modify data of guests.

Comment 8 Summer Long 2017-09-19 06:11:23 UTC 
Mitigation:

To mitigate the flaw, use an overcloud post-deploy script[1] to do the following on all overcloud nodes:

key=/etc/ceph/ceph.client.openstack.keyring
chown root:root $key
chmod 600 $key
setfacl -m u:glance:r $key 
setfacl -m u:cinder:r $key
setfacl -m u:nova:r $key
setfacl -m u: gnocchi:r $key

If not using Red Hat OpenStack Platform director, then run the commands above manually on each overcloud node, 
Warning: Only running 'chmod 600 $key' alone (without an ACL) will prevent OpenStack from reading the key.
