    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.
    
    A use-after-free flaw was found in the way several libvirt block APIs
    handled domain jobs. A remote attacker able to establish a read-only
    connection to libvirtd could use this flaw to crash libvirtd or,
    potentially, execute arbitrary code with the privileges of the libvirtd
    process (usually root). (CVE-2013-6458)
    
    A race condition was found in the way libvirtd handled keepalive
    initialization requests when the connection was closed prior to
    establishing connection credentials. An attacker able to establish a
    read-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:
    
    * A race condition was possible between a thread starting a virtual machine
    with a guest agent configured (regular start-up or while migrating) and a
    thread that was killing the VM process (or the process crashing). The race
    could cause the monitor object to be freed by the thread that killed the VM
    process, which was later accessed by the thread that was attempting to
    start the VM, resulting in a crash. This issue was fixed by checking the
    state of the VM after the attempted connection to the guest agent; if the
    VM in the meantime exited, no other operations are attempted. (BZ#1055578)
    
    All libvirt users 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/site/articles/11258
    
    5. Bugs fixed (https://bugzilla.redhat.com/):
    
    1048631 - CVE-2013-6458 qemu: job usage issue in several APIs leading to libvirtd crash
    1052957 - CVE-2014-1447 libvirt: denial of service with keepalive
    1055578 - bidirectional VMs migration between 2 hosts fail on VM doesn't exist / fatal error
