                   Red Hat Security Advisory

Synopsis:          Moderate: Red Hat Ceph Storage 2.1 security and bug fix update
Advisory ID:       RHSA-2016:2954-01
Product:           Red Hat Ceph Storage
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2016-2954.html
Issue date:        2016-12-15
CVE Names:         CVE-2016-9579 
=====================================================================

1. Summary:

An update is now available for Red Hat Ceph Storage 2.1. 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.

2. Relevant releases/architectures:

Red Hat Ceph Storage MON 2 - x86_64
Red Hat Ceph Storage OSD 2 - x86_64
Red Hat Ceph Storage Tools 2 - x86_64

3. Description:

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)

Bug Fix(es):

* Due to a bug in the underlying source code, OSD nodes sometimes looped
through the entire placement group, not only the requested segment, during
the scrubbing process. Consequently, in some cases, the OSD nodes reached
the 'suicide timeout' and terminated. This bug has been fixed, and OSD
nodes no longer terminate due to the described problem. (BZ#1394007)

* Due to changes in encoding of the OSD map in the ceph package version
10.2.2, upgrading from Red Hat Ceph Storage 1.3 to 2.0 sometimes led to
serious performance issues on large clusters that contain hundreds of OSDs.
With this update, the underlying source code has been improved, and
upgrading from 1.3 to 2.0 works as expected. (BZ#1402185)

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

5. Bugs fixed (https://bugzilla.redhat.com/):

1394007 - filestore: can get stuck in an unbounded loop during scrub
1402185 - jewel: osd: condition OSDMap encoding on features
1403003 - An anonymous user can provoke an abort() of the RGW server by sending a request with an invalid HTTP Origin header, against buckets with CORS AllowedOrigin rules.
1403245 - CVE-2016-9579 ceph: Object Gateway server DoS by sending invalid cross-origin HTTP request
