1. Summary:

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.

2. Relevant releases/architectures:

Red Hat JBoss Enterprise Application Platform 6.4 for RHEL 6 Server - noarch

3. Description:

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).
