"A security update is now available for Red Hat JBoss Enterprise
Application Platform from the Customer Portal.

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.

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

This asynchronous patch is a security update for JGroups package in
Red Hat JBoss Enterprise Application Platform 6.4 More information
about this vulnerability is available at:
https://access.redhat.com/articles/2360521

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)

The CVE-2016-2141 issue was discovered by Dennis Reed (Red Hat)."
