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)

More information about this vulnerability is available at:
https://access.redhat.com/articles/2360521

* A directory traversal flaw was found in Tomcat's and JBoss Web's
RequestUtil.java. A remote, authenticated user could use this flaw to
bypass intended SecurityManager restrictions and list a parent directory
via a '/..' in a pathname used by a web application in a getResource,
getResourceAsStream, or getResourcePaths call, as demonstrated by the
$CATALINA_BASE/webapps directory. (CVE-2015-5174)
