    Updated qemu-kvm-rhev packages that fix one security issue are now
    available for Red Hat Enterprise Linux OpenStack Platform 5.0 for Red Hat
    Enterprise Linux 7.

    2. Relevant releases/architectures:
    
    Red Hat Enterprise Linux OpenStack Platform 5.0 for RHEL 7 - 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.
    
    An information leak flaw was found in the way QEMU's VGA emulator accessed
    frame buffer memory for high resolution displays. A privileged guest user
    could use this flaw to leak memory contents of the host to the guest by
    setting the display to use a high resolution in the guest. (CVE-2014-3615)
    
    This issue was discovered by Laszlo Ersek of Red Hat.
    
    All users of qemu-kvm-rhev are advised to upgrade to these updated
    packages, which contain a backported patch to correct this issue. 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.
