Synopsis
========

Multiple vulnerabilities have been found in Xen, the worst of which
allows gaining of privileges on the host system.

Background
==========

Xen is a bare-metal hypervisor.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-emulation/xen < 4.6.3-r3 >= 4.6.3-r3
2 app-emulation/xen-tools < 4.6.3-r2 >= 4.6.3-r2
-------------------------------------------------------------------
2 affected packages

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

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

Impact
======

A malicious guest administrator could escalate their privileges on the
host system or cause a Denial of Service. Additionally, a malicious
unprivileged guest user may be able to obtain or corrupt sensitive
information (including cryptographic material) in other programs in the
same guest.

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-4.6.3-r3"

All Xen tools users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot -v ">=app-emulation/xen-tools-4.6.3-r2
