"An update is now available for Red Hat Ceph Storage 1.3. This erratum
is for Red Hat Ceph Storage that runs on Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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

Security Fix(es) :

* A flaw was found in the way Ceph Object Gateway would process
cross-origin HTTP requests if the CORS policy was set to allow origin
on a bucket. A remote unauthenticated attacker could use this flaw to
cause denial of service by sending a specially crafted cross-origin
HTTP request. (CVE-2016-9579)"
