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

 

1. Summary:

 

Updated openstack-nova packages that fix two security issues and multiple

bugs are now available for Red Hat OpenStack Folsom.

 

The Red Hat Security Response Team has rated this update as having

important 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-nova packages provide OpenStack Compute (code name Nova), a

cloud computing fabric controller.

 

The openstack-nova packages have been upgraded to upstream version

2012.2.2, which provides a number of bug fixes over the previous version.

 

This update also fixes the following security issues:

 

It was found that the boot-from-volume feature in nova-volume did not

correctly validate if the user attempting to boot an image was permitted

to do so. An authenticated user could use this flaw to bypass

intended restrictions, allowing them to boot images they would otherwise

not have access to, exposing data stored in other users' images. This

issue did not affect configurations using the Cinder block storage

mechanism, which is the default in Red Hat OpenStack. (CVE-2013-0208)

 

When OpenStack Nova was configured to provide guest instances with libvirt

and said guests used LVM-backed ephemeral storage

("libvirt_images_type=lvm" in "/etc/nova/nova.conf"), the contents of the

physical volume were not wiped before the volume was returned to the system

for use by a different guest instance. This could lead to a new instance

being able to access files and data from a previous instance. This issue

did not affect configurations using the Cinder block storage mechanism,

which is the default in Red Hat OpenStack. (CVE-2012-5625)

 

Red Hat would like to thank the OpenStack project for reporting these

issues. Upstream acknowledges Phil Day as the original reporter of

CVE-2013-0208, and Eric Windisch as the original reporter of CVE-2012-5625.

 

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

packages, which correct these issues. After installing the updated

packages, the Nova running services will be restarted automatically.

 

4. Solution:
