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

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

Impact
======

A local attacker could potentially execute arbitrary code with
privileges of Xen (QEMU) process on the host, gain privileges on the
host system, or cause a Denial of Service condition.

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-4.7.2-r1:0"

All Xen Tools users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.7.2:0"

All Xen pvgrub users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=app-emulation/xen-pvgrub-4.7.2:0"
