Summary: 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. 2. Relevant releases/architectures: RHEL Desktop Multi OS (v. 5 client) - i386, x86_64 RHEL Virtualization (v. 5 server) - i386, ia64, x86_64 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) 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. 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 5.
