Topic

An updated rhev-hypervisor6 package that fixes two security issues and
various bugs is now available.

The Red Hat Security Response Team has rated this update as having
important security impact. Common Vulnerability Scoring System (CVSS) base
scores, which give detailed severity ratings, are available for each
vulnerability from the CVE links in the References section.

Description

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.

A flaw was found in the way KVM initialized a guest's registered pv_eoi
(paravirtualized end-of-interrupt) indication flag when entering the guest.
An unprivileged guest user could potentially use this flaw to crash the
host. (CVE-2013-1935)

A flaw was found in the way unexpected fields in guestInfo dictionaries
were processed. A privileged guest user could potentially use this flaw to
make the host the guest is running on unavailable to the management server.
(CVE-2013-0167)

Red Hat would like to thank IBM for reporting the CVE-2013-1935 issue. The
CVE-2013-0167 issue was discovered by Dan Kenigsberg of the Red Hat
Enterprise Virtualization team.

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-2013-1962 (libvirt issue)

CVE-2013-2017 and CVE-2013-1943 (kernel issues)

CVE-2012-6137 (subscription-manager issue)

This update also contains the fixes from the following errata:

  • vdsm: RHSA-2013:0886, which adds support for Red Hat Enterprise

Virtualization 3.2 clusters.

  • ovirt-node: RHBA-2013:0908

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.

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

Solution

This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
