Advisory URL:      https://access.redhat.com/errata/RHSA-2016:1346

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

1. Summary:

An update is now available for Red Hat JBoss Data Virtualization.

Red Hat Product Security has rated this update as having a security impact
of Critical. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available for each vulnerability from
the CVE link(s) in the References section.

2. Description:

Red Hat JBoss Data Virtualization is a lean data integration solution that
provides easy, real-time, and unified data access across disparate sources
to multiple applications and users. JBoss Data Virtualization makes data
spread across physically distinct systems - such as multiple databases, XML
files, and even Hadoop systems - appear as a set of tables in a local
database.

Security Fix(es):

* It was found that JGroups did not require necessary headers for encrypt
and auth protocols from new nodes joining the cluster. An attacker could
use this flaw to bypass security restrictions, and use this vulnerability
to send and receive messages within the cluster, leading to information
disclosure, message spoofing, or further possible attacks. (CVE-2016-2141)

This issue was discovered by Dennis Reed (Red Hat).

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). Before applying the update, back up your
existing Red Hat JBoss Data Virtualization installation (including its
databases, applications, configuration files, and so on).

Note that it is recommended to halt the Red Hat JBoss Data Virtualization
server by stopping the JBoss Application Server process before installing
this update, and then after installing the update, restart the Red Hat
JBoss Data Virtualization server by starting the JBoss Application Server
process.
