Synopsis
========

Multiple vulnerabilities have been found in Xen, the worst of which
could allow for privilege escalation.

Background
==========

Xen is a bare-metal hypervisor.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-emulation/xen < 4.9.1-r1 >= 4.9.1-r1
2 app-emulation/xen-tools < 4.9.1-r1 >= 4.9.1-r1
-------------------------------------------------------------------
2 affected packages

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

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

Impact
======

A local attacker could potentially execute arbitrary code with the
privileges of the 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-4.9.1-r1"

All Xen tools users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.9.1-r1"
