"An update for jboss-ec2-eap is now available for Red Hat JBoss
Enterprise Application Platform 6.4 for RHEL 6.

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.

The jboss-ec2-eap package provide scripts for Red Hat JBoss Enterprise
Application Platform running on the Amazon Web Services (AWS) Elastic
Compute Cloud (EC2).

With this update, the jboss-ec2-eap package has been updated to ensure
compatibility with Red Hat JBoss Enterprise Application Platform
6.4.12.

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)."
