"Updated subscription-manager packages that fix one security issue are
now available for Red Hat Enterprise Linux 5 and 6.

The Red Hat Security Response Team has rated this update as having
moderate 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 subscription-manager packages provide programs and libraries to
allow users to manage subscriptions and yum repositories from the Red
Hat Entitlement platform.

It was discovered that the rhn-migrate-classic-to-rhsm tool did not
verify the Red Hat Network Classic server's X.509 certificate when
migrating system profiles registered with Red Hat Network Classic to
Certificate-based Red Hat Network. An attacker could use this flaw to
conduct man-in-the-middle attacks, allowing them to obtain the user's
Red Hat Network credentials. (CVE-2012-6137)

This issue was discovered by Florian Weimer of the Red Hat Product
Security Team.

All users of subscription-manager are advised to upgrade to these
updated packages, which contain a backported patch to fix this issue."

"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.

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."
