Title:	RedHat Update for libvirt RHSA-2012:1202-01
Summary:	The remote host is missing an update for the 'libvirt'; package(s) announced via the referenced advisory.
Description:	Summary: The remote host is missing an update for the 'libvirt' package(s) announced via the referenced advisory. Vulnerability Insight: 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. A flaw was found in libvirtd's RPC call handling. An attacker able to establish a read-only connection to libvirtd could trigger this flaw with a specially-crafted RPC command that has the number of parameters set to 0, causing libvirtd to access invalid memory and crash. (CVE-2012-3445) This update also fixes the following bugs: * Previously, repeatedly migrating a guest between two machines while using the tunnelled migration could cause the libvirt daemon to lock up unexpectedly. The bug in the code for locking remote drivers has been fixed and repeated tunnelled migrations of domains now work as expected. (BZ#847946) * Previously, when certain system locales were used by the system, libvirt could issue incorrect commands to the hypervisor. This bug has been fixed and the libvirt library and daemon are no longer affected by the choice of the user locale. (BZ#847959) 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. Affected Software/OS: libvirt on Red Hat Enterprise Linux Desktop (v. 6), Red Hat Enterprise Linux Server (v. 6), Red Hat Enterprise Linux Workstation (v. 6) Solution: Please Install the Updated Packages. CVSS Score: 3.5 CVSS Vector: AV:N/AC:M/Au:S/C:N/I:N/A:P
