Synopsis
========

Multiple vulnerabilities have been found in Xen, the worst of which
could lead to the execution of arbitrary code on the host system.

Background
==========

Xen is a bare-metal hypervisor.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected

Description
===========

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

Impact
======

A local attacker could possibly execute arbitrary code with the
privileges of the process, could gain privileges on the host system,
cause a Denial of Service condition, or obtain sensitive information.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Xen users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-emulation/xen-4.7.1-r4"

All Xen Tools users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.7.1-r4"

All Xen PvGrub users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.7.1-r1"
