(Red Hat Issues Fix for Red Hat Enterprise Virtualization Hypervisor) OpenSSL TLS Heartbeat Buffer Overread Lets Remote Users Obtain Potentially Sensitive Information
SecurityTracker Alert ID:  1030056
SecurityTracker URL:  http://securitytracker.com/id/1030056
CVE Reference:   CVE-2014-0160   (Links to External Site)
Date:  Apr 11 2014
Impact:   Disclosure of authentication information, Disclosure of system information, Disclosure of user information
Fix Available:  Yes  Vendor Confirmed:  Yes  Exploit Included:  Yes  

Description:   A vulnerability was reported in OpenSSL. A remote user can obtain potentially sensitive information. Red Hat Enterprise Virtualization Hypervisor is affected.

A remote client or server can trigger a buffer overread in the processing of the TLS heartbeat extension to obtain up to 64k of memory (per heartbeat request), potentially including encryption keys.

The vulnerability was introduced to the source code in December 2011 and to release version 1.0.1 in March 2012.

[Editor's note: This vulnerability is known as the OpenSSL heartbleed vulnerability.]

Neel Mehta of Google Security reported this vulnerability.

Impact:   A remote user can obtain potentially sensitive information, including encryption keys.
Solution:   Red Hat has issued a fix for Red Hat Enterprise Virtualization Hypervisor.

=====================================================================
                   Red Hat Security Advisory

Synopsis:          Important: rhev-hypervisor6 security update
Advisory ID:       RHSA-2014:0396-01
Product:           Red Hat Enterprise Virtualization
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-0396.html
Issue date:        2014-04-10
CVE Names:         CVE-2014-0160 
=====================================================================

1. Summary:

An updated rhev-hypervisor6 package that fixes one security issue is now
available for Red Hat Enterprise Virtualization Hypervisor 3.2.

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.

Important: This update is an emergency security fix being provided outside
the scope of the published support policy for Red Hat Enterprise
Virtualization listed in the References section. In accordance with the
support policy for Red Hat Enterprise Virtualization, Red Hat Enterprise
Virtualization Hypervisor 3.2 will not receive future security updates.

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

An information disclosure flaw was found in the way OpenSSL handled TLS and
DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server
could send a specially crafted TLS or DTLS Heartbeat packet to disclose a
limited portion of memory per request from a connected client or server.
Note that the disclosed portions of memory could potentially include
sensitive information such as private keys. (CVE-2014-0160)

Red Hat would like to thank the OpenSSL project for reporting this issue.
Upstream acknowledges Neel Mehta of Google Security as the original
reporter.

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

4. 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
https://access.redhat.com/site/articles/11258
