Synopsis
=======
Multiple vulnerabilities have been found in Xen, allowing attackers on
a Xen Virtual Machine to execute arbitrary code, cause Denial of
Service, or gain access to data on the host.

Background
=========
Xen is a bare-metal hypervisor.

Affected packages
================
    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

    -------------------------------------------------------------------
     3 affected packages

Description
==========
Multiple vulnerabilities have been discovered in Xen. Please review the
CVE identifiers referenced below for details.

Impact
=====
Guest domains could possibly gain privileges, execute arbitrary code,
or cause a Denial of Service on the host domain (Dom0). Additionally,
guest domains could gain information about other virtual machines
running on the same host or read arbitrary files on the host.

Workaround
=========
The CVEs listed below do not currently have fixes, but only apply to
Xen setups which have "tmem" specified on the hypervisor command line.
TMEM is not currently supported for use in production systems, and
administrators using tmem should disable it.
Relevant CVEs:
* CVE-2012-2497
* CVE-2012-6030
* CVE-2012-6031
* CVE-2012-6032
* CVE-2012-6033
* CVE-2012-6034
* CVE-2012-6035
* CVE-2012-6036

Resolution
=========
All Xen users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-emulation/xen-4.2.2-r1"

All Xen-tools users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.2.2-r3"

All Xen-pvgrub users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.2.2-r1"
