Updated libvirt packages that fix one security issue, multiple bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.

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.
