    Package        : qemu-kvm
    CVE ID         : CVE-2014-3689 CVE-2014-7815
    
    Several vulnerabilities were discovered in qemu-kvm, a full
    virtualization solution on x86 hardware.
    
    CVE-2014-3689
    
        The Advanced Threat Research team at Intel Security reported that
        guest provided parameter were insufficiently validated in
        rectangle functions in the vmware-vga driver. 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.
    
    CVE-2014-7815
    
        James Spadaro of Cisco reported insufficiently sanitized
        bits_per_pixel from the client in the QEMU VNC display driver. An
        attacker having access to the guest's VNC console could use this
        flaw to crash the guest.
    
    For the stable distribution (wheezy), these problems have been fixed in
    version 1.1.2+dfsg-6+deb7u5.
    
    We recommend that you upgrade your qemu-kvm packages.
