"An updated ceph package that fixes one security issue is now available
for Red Hat Ceph Storage 1.3 for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Moderate
security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

Red Hat Ceph Storage is a massively scalable, open, software-defined
storage platform that combines the most stable version of Ceph with a
Ceph management platform, deployment tools, and support services.

A flaw was found in the way handle_command() function would validate
prefix value from user. An authenticated attacker could send a
specially crafted prefix value resulting in ceph monitor
crash.(CVE-2016-5009)

Upstream acknowledges Xiaoxi Chen as the original reporter of
CVE-2016-5009.

All ceph users are advised to upgrade to this updated package, which
contains backported patches to correct this issue."
