    1. Summary:
    
    Updated qemu-kvm-rhev packages that fix several security issues are now
    available for Red Hat Enterprise Linux OpenStack Platform 3.0 and 4.0.
    
    The Red Hat Security Response Team has rated this update as having Moderate
    security impact. Common Vulnerability Scoring System (CVSS) base scores,
    which give detailed severity ratings, are available for each vulnerability
    from the CVE links in the References section.
    
    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux OpenStack Platform 3.0 - x86_64
    Red Hat Enterprise Linux OpenStack Platform 4.0 - x86_64
    
    3. Description:
    
    KVM (Kernel-based Virtual Machine) is a full virtualization solution for
    Linux on AMD64 and Intel 64 systems. The qemu-kvm-rhev package provides the
    user-space component for running virtual machines using KVM in environments
    managed by Red Hat Enterprise Linux OpenStack Platform.
    
    Multiple buffer overflow, input validation, and out-of-bounds write flaws
    were found in the way the virtio, virtio-net, virtio-scsi, and usb drivers
    of QEMU handled state loading after migration. A user able to alter the
    savevm data (either on the disk or over the wire during migration) could
    use either of these flaws to corrupt QEMU process memory on the
    (destination) host, which could potentially result in arbitrary code
    execution on the host with the privileges of the QEMU process.
    (CVE-2013-4148, CVE-2013-4151, CVE-2013-4535, CVE-2013-4536, CVE-2013-4541,
    CVE-2013-4542, CVE-2013-6399, CVE-2014-0182, CVE-2014-3461)
    
    An out-of-bounds memory access flaw was found in the way QEMU's IDE device
    driver handled the execution of SMART EXECUTE OFFLINE commands.
    A privileged guest user could use this flaw to corrupt QEMU process memory
    on the host, which could potentially result in arbitrary code execution on
    the host with the privileges of the QEMU process. (CVE-2014-2894)
    
    These issues were discovered by Michael S. Tsirkin, Anthony Liguori and 
    Michael Roth of Red Hat: CVE-2013-4148, CVE-2013-4151, CVE-2013-4535,
    CVE-2013-4536, CVE-2013-4541, CVE-2013-4542, CVE-2013-6399, CVE-2014-0182,
    and CVE-2014-3461.
    
    All users of qemu-kvm-rhev are advised to upgrade to these updated
    packages, which contain backported patches to correct these issues. After
    installing this update, shut down all running virtual machines. Once all
    virtual machines have shut down, start them again for this update to take
    effect.
    
    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
