The libvirt library is a C API for managing and interacting with thevirtualization capabilities of Linux and other operating systems.In addition, libvirt provides tools for remote management ofvirtualized systems.A use-after-free flaw was found in the way several libvirt block APIshandled domain jobs. A remote attacker able to establish a read-onlyconnection to libvirtd could use this flaw to crash libvirtd or,potentially, execute arbitrary code with the privileges of the libvirtdprocess (usually root). (CVE-2013-6458)A race condition was found in the way libvirtd handled keepaliveinitialization requests when the connection was closed prior toestablishing connection credentials. An attacker able to establish aread-only connection to libvirtd could use this flaw to crash libvirtd,resulting in a denial of service. (CVE-2014-1447)This update also fixes the following bug:All libvirt users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing theupdated packages, libvirtd will be restarted automatically.
