  script_tag(name:"insight", value:"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':
[link moved to references]
 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.
