Advisory URL: https://rhn.redhat.com/errata/RHSA-2012-0748.html
Issue date: 2012-06-20
CVE Names: CVE-2012-2693
=====================================================================
1. Summary:
Updated libvirt packages that fix one security issue, multiple bugs, and
add various enhancements are now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

3. Description:
The libvirt library is a C API for managing and interacting with the
virtualization capabilities of Linux and other operating systems. In
addition, libvirt provides tools for remote management of virtualized
systems.
Bus and device IDs were ignored when attempting to attach multiple USB
devices with identical vendor or product IDs to a guest. This could result
in the wrong device being attached to a guest, giving that guest root
access to the device. (CVE-2012-2693)
These updated libvirt packages include numerous bug fixes and enhancements.
Space precludes documenting all of these changes in this advisory. Users
are directed to the Red Hat Enterprise Linux 6.3 Technical Notes for
information on the most significant of these changes.
All users of libvirt are advised to upgrade to these updated packages,
which fix these issues and add these enhancements. After installing the
updated packages, libvirtd must be restarted ("service libvirtd restart")
for this update to take effect.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
https://access.redhat.com/knowledge/articles/11258
