   An update that fixes three vulnerabilities is now available.

Description:


   Three security issues were found in XEN.

   Two security issues are fixed by this update:

   *

   CVE-2012-0217: 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-2012-0218: Also a guest user could crash the
   guest XEN kernel due to a protection fault bounce.

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

   *

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

   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.
