3. Description:

The eap7-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 eap7-jboss-ec2-eap package has been updated to ensure
compatibility with Red Hat JBoss Enterprise Application Platform 7.0.2.
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).
