    Package        : qemu
    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, a fast processor
    emulator. 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-6a+deb7u6.
    
    We recommend that you upgrade your qemu packages.
