Updated libvirt packages that fix one security issue and several bugs are
now available for Red Hat Enterprise Linux 5.

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.

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

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)

This update also fixes the following bugs:

* Previously, the libvirtd library failed to set the autostart flags for
already defined QEMU domains. This bug has been fixed, and the domains can
now be successfully marked as autostarted. (BZ#675319)

* Prior to this update, the virFileAbsPath() function was not taking into
account the slash ("/") directory separator when allocating memory for
combining the cwd() function and a path. This behavior could lead to a
memory corruption. With this update, a transformation to the virAsprintff()
function has been introduced into virFileAbsPath(). As a result, the
aforementioned behavior no longer occurs. (BZ#680289)

* With this update, a man page of the virsh user interface has been
enhanced with information on the "domxml-from-native" and
"domxml-to-native" commands. A correct notation of the format argument has
been clarified. As a result, confusion is avoided when setting the format
argument in the described commands. (BZ#783001)

All users of libvirt are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. After installing
the updated packages, libvirtd will be restarted automatically.
