Summary
Red Hat Security Advisory: openstack-nova security and bug fix update

Notes

Topic
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.
Details
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.
