    Package : xen-qemu-dm-4.0
    Vulnerability : multiple
    Problem type : local
    Debian-specific: no
    CVE ID : CVE-2012-3515 CVE-2012-4411

    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.
