1. Summary:

An update is now available for Red Hat JBoss Enterprise Application

Red Hat Product Security has rated this update as having a security impact
of Important. 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 Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

This release of Red Hat JBoss Enterprise Application Platform 6.4.14 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.13,
and includes bug fixes and enhancements, which are documented in the
Release Notes document linked to in the References.

Security Fix(es):

* It was discovered that EAP packages in certain versions of Red Hat
Enterprise Linux use incorrect permissions for /etc/sysconfig/jbossas
configuration files. The file is writable to jboss group (root:jboss, 664).
On systems using classic /etc/init.d init scripts (i.e. on Red Hat
Enterprise Linux 6 and earlier), the file is sourced by the jboss init
script and its content executed with root privileges when jboss service is
started, stopped, or restarted. (CVE-2016-8657) 

* It was discovered that a programming error in the processing of HTTPS
requests in the Apache Tomcat servlet and JSP engine may result in denial
of service via an infinite loop. (CVE-2017-6056)

* It was found that GZIPInterceptor is enabled when not necessarily
required in RESTEasy. An attacker could use this flaw to launch a Denial of
Service attack. (CVE-2016-6346)

Red Hat would like to thank Mikhail Egorov (Odin) for reporting the
CVE-2016-6346 issue.

3. Solution:

Before applying this update, back up your existing Red Hat JBoss Enterprise
Application Platform installation and deployed applications.
