1. Summary:

An update is now available for Red Hat JBoss Enterprise Application
Platform.

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 6.4.13 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.12,
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 the jboss init script performed unsafe file
handling which could result in local privilege escalation. (CVE-2016-8656)

* It was discovered that the code that parsed the HTTP request line
permitted invalid characters. This could be exploited, in conjunction with
a proxy that also permitted the invalid characters but with a different
interpretation, to inject data into the HTTP response. By manipulating the
HTTP response the attacker could poison a web-cache, perform an XSS attack
and/or obtain sensitive information from requests other then their own.
(CVE-2016-6816)

* An EAP feature to download server log files allows logs to be available
via GET requests making them vulnerable to cross-origin attacks. An
attacker could trigger the user's browser to request the log files
consuming enough resources that normal server functioning could be
impaired. (CVE-2016-8627)

* It was discovered that when configuring RBAC and marking information as
sensitive, users with a Monitor role are able to view the sensitive
information. (CVE-2016-7061)

The CVE-2016-8627 issue was discovered by Darran Lofthouse and Brian
Stansberry (Red Hat).
