    Package        : qemu-kvm
    CVE ID         : CVE-2014-8106
    
    Paolo Bonzini of Red Hat discovered that the blit region checks were
    insufficient in the Cirrus VGA emulator in qemu-kvm, a full
    virtualization solution on x86 hardware. A privileged guest user could
    use this flaw to write into qemu address space on the host, potentially
    escalating their privileges to those of the qemu host process.
    
    For the stable distribution (wheezy), this problem has been fixed in
    version 1.1.2+dfsg-6+deb7u6.
    
    We recommend that you upgrade your qemu-kvm packages.
