"Three security issues were found in XEN.

Two security issues are fixed by this update :

  - Due to incorrect fault handling in the XEN hypervisor it
    was possible for a XEN guest domain administrator to
    execute code in the XEN host environment.
    (CVE-2012-0217)

  - Also a guest user could crash the guest XEN kernel due
    to a protection fault bounce. (CVE-2012-0218)

The third fix is changing the Xen behaviour on certain hardware :

  - The issue is a denial of service issue on older pre-SVM
    AMD CPUs (AMD Erratum 121). (CVE-2012-2934)

    AMD Erratum #121 is described in 'Revision Guide for AMD
    Athlon 64 and AMD Opteron Processors':
    http://support.amd.com/us/Processor_TechDocs/25759.pdf

    The following 130nm and 90nm (DDR1-only) AMD processors
    are subject to this erratum :

o

First-generation AMD-Opteron(tm) single and dual core
processors in either 939 or 940 packages :

  - AMD Opteron(tm) 100-Series Processors

  - AMD Opteron(tm) 200-Series Processors

  - AMD Opteron(tm) 800-Series Processors

  - AMD Athlon(tm) processors in either 754, 939 or 940
    packages

  - AMD Sempron(tm) processor in either 754 or 939 packages

  - AMD Turion(tm) Mobile Technology in 754 package This
    issue does not effect Intel processors.

    The impact of this flaw is that a malicious PV guest
    user can halt the host system.

    As this is a hardware flaw, it is not fixable except by
    upgrading your hardware to a newer revision, or not
    allowing untrusted 64bit guestsystems.

    The patch changes the behaviour of the host system
    booting, which makes it unable to create guest machines
    until a specific boot option is set.

    There is a new XEN boot option 'allow_unsafe' for GRUB
    which allows the host to start guests again.

    This is added to /boot/grub/menu.lst in the line looking
    like this :

    kernel /boot/xen.gz .... allow_unsafe

    Note: .... in this example represents the existing boot
    options for the host."
