CentOS Errata and Security Advisory CESA-2012:0748
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.
