"An update for eap7-jboss-ec2-eap is now available for Red Hat JBoss
Enterprise Application Platform 7.0 for RHEL 6 and Red Hat JBoss
Enterprise Application Platform 7.0 for RHEL 7.

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.

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 7.0.6.

Refer to the JBoss Enterprise Application Platform 7.0.6 Release
Notes, linked to in the References section, for information on the
most significant bug fixes and enhancements included in this release.

Security Fix(es) :

* It was discovered that under certain conditions RESTEasy could be
forced to parse a request with YamlProvider, resulting in
unmarshalling of potentially untrusted data. An attacker could
possibly use this flaw execute arbitrary code with the permissions of
the application using RESTEasy. (CVE-2016-9606)

* It was found that the log file viewer in Red Hat JBoss Enterprise
Application 6 and 7 allows arbitrary file read to authenticated user
via path traversal. (CVE-2017-2595)

* 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, or obtain sensitive information from requests
other than their own. (CVE-2017-2666)

* It was found that with non-clean TCP close, Websocket server gets
into infinite loop on every IO thread, effectively causing DoS.
(CVE-2017-2670)

Red Hat would like to thank Moritz Bechler (AgNO3 GmbH & Co. KG) for
