1. Summary:

Updated packages that provide Red Hat JBoss Enterprise Application Platform
7.0.2, fix several bugs, and add various enhancements are now available
from the Customer Portal.

2. Description:

Red Hat JBoss Enterprise Application Platform 7 is an application server
that serves as a middleware platform and is built on open standards and
compliant with the Java EE 7 specification.

This release serves as a replacement for Red Hat JBoss Enterprise
Application Platform 7.0.1. It includes bug fixes and enhancements. Refer
to the JBoss Enterprise Application Platform 7.0.2 Release Notes linked to
in the References section for information about the most significant bug
fixes and enhancements included in this release.

Security Fix(es):

* It was found that the Java Standard Tag Library (JSTL) allowed the
processing of untrusted XML documents to utilize external entity
references, which could access resources on the host system and,
potentially, allowing arbitrary code execution. (CVE-2015-0254)

* It was reported that EAP 7 Application Server/Undertow web server is
vulnerable to the injection of arbitrary HTTP headers, and also response
splitting, due to insufficient sanitization and validation of user input
before the input is used as part of an HTTP header value. (CVE-2016-4993)

* The domain controller will not propagate its administrative RBAC
configuration to some slaves. An attacker could use this to escalate their
privileges. (CVE-2016-5406)

Red Hat would like to thank Calum Hutton (NCC Group) and Mikhail Egorov
(Odin) for reporting CVE-2016-4993. The CVE-2016-5406 issue was discovered
by Tomaz Cerar (Red Hat).

3. Solution:

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

The References section of this erratum contains a download link (you must
log in to download the update).

The JBoss server process must be restarted for the update to take effect.

4. Bugs fixed (https://bugzilla.redhat.com/):
