Description
It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack.

Remediation
Red Hat statement
Red Hat OpenStack Platform ships the flawed package, however RHOSP deployments use the ceph package directly from the Ceph channel. A RHOSP ceph update will therefore not be provided at this time, but please ensure that the underlying Red Hat Ceph Storage is updated.
