"An update is now available for Red Hat Ceph Storage 2.1 that fix one
security issue, multiple bugs, and add various enhancements. This
erratum is applicable for Red Hat Ceph Storage that runs on RHEL 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.

The following packages have been upgraded to a newer upstream version:
ceph (10.2.3), ceph-deploy (1.5.36), calamari-server (1.4.9),
nfs-ganesha (2.4.0), ceph-iscsi-config (1.5), libntirpc (1.4.1),
ceph-iscsi-tools (1.1). (BZ# 1340004, BZ#1349999)

Security Fix(es) :

* A flaw was found in the way Ceph Object Gateway handles POST object
requests. An authenticated attacker could launch a denial of service
attack by sending null or specially crafted POST object requests.
(CVE-2016-8626)

Bug Fix(es) and Enhancement(s) :

For detailed information on changes in this release, see the Red Hat
Ceph Storage 2.1 Release Notes available at :

https://access.redhat.com/documentation/en/red-hat-ceph-storage/2.1/si
ngle/ release-notes/

All users of Red Hat Ceph Storage are advised to upgrade to these
updated packages."
