=====================================================================

1. Summary:

An updated rhev-hypervisor6 package that fixes one security issue and
various bugs 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.

2. Relevant releases/architectures:

RHEV Hypervisor for RHEL-6 - noarch

3. 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.

It was discovered that the fix for the CVE-2013-1619 issue released via
RHSA-2013:0636 introduced a regression in the way GnuTLS decrypted TLS/SSL
encrypted records when CBC-mode cipher suites were used. A remote attacker
could possibly use this flaw to crash a server or client application that
uses GnuTLS. (CVE-2013-2116)

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-2013-2174 (curl issue)

CVE-2012-6548, CVE-2013-0914, CVE-2013-1848, CVE-2013-2128, CVE-2013-2634,
CVE-2013-2635, CVE-2013-2852, CVE-2013-3222, CVE-2013-3224, CVE-2013-3225,
and CVE-2013-3301 (kernel issues)

CVE-2002-2443 (krb5 issue)

CVE-2013-1950 (libtirpc issue)

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. 

This update also contains the fixes from the following errata:

* ovirt-node: RHBA-2013:1077

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