"A jboss-ec2-eap update is now available for Red Hat JBoss Enterprise
Application Platform 6.4.7 on Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having a security
impact of Moderate. 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.

The jboss-ec2-eap packages provide scripts for Red Hat JBoss
Enterprise Application Platform running on the Amazon Web Services
(AWS) Elastic Compute Cloud (EC2). With this update, the packages have
been updated to ensure compatibility with Red Hat JBoss Enterprise
Application Platform 6.4.7.

Security Fix(es) :

* A read-timeout flaw was found in the HTTPS NIO Connector handling of
SSL handshakes. A remote, unauthenticated attacker could create a
socket and cause a thread to remain occupied indefinitely so long as
the socket remained open (denial of service). (CVE-2016-2094)

* It was found that Tomcat would keep connections open after
processing requests with a large enough request body. A remote
attacker could potentially use this flaw to exhaust the pool of
available connections and preventing further, legitimate connections
to the Tomcat server to be made. (CVE-2014-0230)

The CVE-2016-2094 issue was discovered by Aaron Ogburn of Red Hat."
