                   Red Hat Security Advisory

Synopsis:          Moderate: Red Hat Enterprise Virtualization Manager 3.4.2 update
Advisory ID:       RHSA-2014:1161-01
Product:           Red Hat Enterprise Virtualization
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2014-1161.html

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

1. Summary:

Red Hat Enterprise Virtualization Manager 3.4.2 is now available.

Red Hat Product Security 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.

2. Relevant releases/architectures:

RHEV-M 3.4 - noarch

3. Description:

Red Hat Enterprise Virtualization Manager is a visual tool for centrally
managing collections of virtual servers running Red Hat Enterprise Linux
and Microsoft Windows. This package also includes the Red Hat Enterprise
Virtualization Manager API, a set of scriptable commands that give
administrators the ability to perform queries and operations on Red Hat
Enterprise Virtualization Manager.

The Manager is a JBoss Application Server application that provides several
interfaces through which the virtual environment can be accessed and
interacted with, including an Administration Portal, a User Portal, and a
Representational State Transfer (REST) Application Programming Interface
(API).

It was discovered that, when loading XML/RSDL documents, the oVirt Engine
back end module used an insecure DocumentBuilderFactory. A remote,
authenticated attacker could use this flaw to read files accessible to the
user running the ovirt-engine server, and potentially perform other more
advanced XML External Entity (XXE) attacks. (CVE-2014-3573)

This issue was discovered by Arun Babu Neelicattu of Red Hat Product
Security.

These updated Red Hat Enterprise Virtualization Manager packages also
include numerous bug fixes and various enhancements. Space precludes
documenting all of these changes in this advisory. Users are directed to
the Red Hat Enterprise Virtualization 3.4 Technical Notes, linked to in the
References, for information on the most significant of these changes.

All Red Hat Enterprise Virtualization Manager users are advised to upgrade
to these updated packages, which resolve these issues and add these
enhancements.

4. Solution:

Before applying this update, make sure all previously released errata
