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 7.0.6.

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)
