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
    -------------------------------------------------------------------
  1  app-emulation/xen           < 4.7.1-r4               >= 4.7.1-r4
  2  app-emulation/xen-tools     < 4.7.1-r4               >= 4.7.1-r4
  3  app-emulation/xen-pvgrub
                                 < 4.7.1-r1               >= 4.7.1-r1
    -------------------------------------------------------------------
     3 affected packages

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"
