"An updated rhev-hypervisor6 package that fixes one security issue and
one bug is now available.

The Red Hat Security Response Team has rated this update as having
important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

The rhev-hypervisor6 package provides a Red Hat Enterprise
Virtualization Hypervisor ISO disk image. The Red Hat Enterprise
Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine
(KVM) hypervisor. It includes everything necessary to run and manage
virtual machines: a subset of the Red Hat Enterprise Linux operating
environment and the Red Hat Enterprise Virtualization Agent.

Note: Red Hat Enterprise Virtualization Hypervisor is only available
for the Intel 64 and AMD64 architectures with virtualization
extensions.

Upgrade Note: If you upgrade the Red Hat Enterprise Virtualization
Hypervisor through the 3.2 Manager administration portal, the Host may
appear with the status of 'Install Failed'. If this happens, place the
host into maintenance mode, then activate it again to get the host
back to an 'Up' state.

A divide-by-zero flaw was found in the apic_get_tmcct() function in
KVM's Local Advanced Programmable Interrupt Controller (LAPIC)
implementation. A privileged guest user could use this flaw to crash
the host. (CVE-2013-6367)

Red Hat would like to thank Andrew Honig of Google for reporting this
issue.

This updated package provides updated components that include fixes
for various security issues. These issues have no security impact on
Red Hat Enterprise Virtualization Hypervisor itself, however. The
security fixes included in this update address the following CVE
numbers :

CVE-2013-2141, CVE-2013-4470, and CVE-2013-6368 (kernel issues)

This update also fixes the following bug :

* The NVR of the rhev-hypervisor6 rpm and the contents of
/etc/system-release did not match. This caused the hypervisor to show
an error message 'A new version is available; an upgrade option will
appear once the Host is moved to maintenance mode.' and suggested an
update, even though the hypervisor was up to date. The version
information in the rpm NVR and /etc/system-release now match. Now, the
hypervisor only suggests updating when there is an update available.
(BZ#1034817)

Users of the Red Hat Enterprise Virtualization Hypervisor are advised
to upgrade to this updated package, which corrects these issues."
