Synopsis: Moderate: openstack-cinder security and enhancement update

Advisory ID: RHSA-2013:0658-01

Product: Red Hat OpenStack

Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0658.html

=====================================================================

 

1. Summary:

 

Updated openstack-cinder packages that fix two security issues and add one

enhancement are now available for Red Hat OpenStack Folsom.

 

The Red Hat Security Response Team 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.

 

2. Relevant releases/architectures:

 

OpenStack Folsom - noarch

 

3. Description:

 

The openstack-cinder packages provide OpenStack Volume (code name Cinder),

which provides services to manage and access block storage volumes for use

by virtual machine instances.

 

A denial of service flaw was found in the Extensible Markup Language (XML)

parser used by Cinder. A remote attacker could use this flaw to send a

specially-crafted request to a Cinder API, causing Cinder to consume an

excessive amount of CPU and memory. (CVE-2013-1664)

 

A flaw was found in the XML parser used by Cinder. If a remote attacker

sent a specially-crafted request to a Cinder API, it could cause Cinder to

connect to external entities, causing a large amount of system load, or

allow an attacker to read files on the Cinder server that are accessible

to the user running Cinder. (CVE-2013-1665)

 

This update also adds the following enhancement:

 

* This update implements a Cinder driver that allows Red Hat Storage to be

used as a back-end for Cinder volumes. To use this driver,

"volume_driver = cinder.volume.glusterfs.GlusterfsDriver" and the

"glusterfs_shares_config" option must be set in "/etc/cinder/cinder.conf",

and the RHSA-2013:0657 openstack-nova update must also be installed. Note

that there is no volume snapshot or clone support when using this driver.

(BZ#892686)

 

All users of openstack-cinder are advised to upgrade to these updated

packages, which fix these issues and add this enhancement. After installing

the updated packages, the Cinder running services will be restarted

automatically.

 

4. Solution:

 

Before applying this update, make sure all previously-released errata

relevant to your system have been applied.
