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
<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.
