Updated Red Hat Storage 2.0 packages that fix multiple security issues,

2. Relevant releases/architectures:

Red Hat Storage is a software only, scale-out storage solution that
provides flexible and agile unstructured data storage for the enterprise.
Multiple insecure temporary file creation flaws were found in Red Hat
Storage server. A local user on the Red Hat Storage server could use these
flaws to cause arbitrary files to be overwritten as the root user via a
symbolic link attack. (CVE-2013-4157)
These issues were discovered by Gowrishankar Rajaiyan of Red Hat and Kurt
Seifried of the Red Hat Security Response Team.
This update also fixes the following bugs:
* Previously, rolling upgrades on a volume caused some processes to abort
which led to a possible corruption of the volume. Yum update aborts with a
message to stop the volume during an update. Now, with this update rolling
upgrades is not supported and it is mandatory to stop the volume before any
'yum update'. (BZ#998649)
* Installing or upgrading the gluster-swift-plugin RPM overwrites
/etc/swift configuration files. Hence, the customer configuration is
overwritten, causing data unavailability. Now, the RPM installs or upgrades
new configuration files with a non-conflicting extension and customer
configuration files are not overwritten, maintaining data availability.
This update also adds the following enhancement:
* A new upgrade script has been added. When Red Hat Storage Server 2.1 is
released, this script will help users upgrade and resubscribe their
Red Hat Storage Server 2.0 Update 6 systems to Red Hat Storage Server 2.1.
All users of Red Hat Storage are advised to upgrade to these updated
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
