    Vulnerability  : multiple

    Multiple vulnerabilities have been discovered in xen-qemu-dm-4.0, the Xen
    Qemu Device Model virtual machine hardware emulator. The Common
    Vulnerabilities and Exposures project identifies the following problems:
    
    CVE-2012-3515:
    
        The device model for HVM domains does not properly handle VT100
        escape sequences when emulating certain devices with a virtual
        console backend. An attacker within a guest with access to the
        vulnerable virtual console could overwrite memory of the device
        model and escalate privileges to that of the device model process.
    
    CVE-2012-4411:
    
        The qemu monitor was enabled by default, allowing administrators of
        a guest to access resources of the host, possibly escalate privileges
        or access resources belonging to another guest.
    
    For the stable distribution (squeeze), these problems have been fixed in
    version 4.0.1-2+squeeze2.
    
    The testing distribution (wheezy), and the unstable distribution (sid),
    no longer contain this package.
    
    We recommend that you upgrade your xen-qemu-dm-4.0 packages.
