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 7.1.

Refer to the JBoss Enterprise Application Platform 7.1 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):

* A Denial of Service can be caused when a long request is sent to EAP 7.
(CVE-2016-7046)

* The jboss init script unsafe file handling resulting in local privilege
escalation. (CVE-2016-8656)

* A deserialization vulnerability via readValue method of ObjectMapper
which allows arbitrary code execution. (CVE-2017-7525) 

* JMSObjectMessage deserializes potentially malicious objects allowing
Remote Code Execution. (CVE-2016-4978)

* Undertow is vulnerable to the injection of arbitrary HTTP headers, and
also response splitting. (CVE-2016-4993)

* The domain controller will not propagate its administrative RBAC
configuration to some slaves leading to escalate their privileges.
(CVE-2016-5406)

* Internal IP address disclosed on redirect when request header Host field
is not set. (CVE-2016-6311)

* Potential EAP resource starvation DOS attack via GET requests for server
log files. (CVE-2016-8627)

* Inefficient Header Cache could cause denial of service. (CVE-2016-9589)

* The log file viewer allows arbitrary file read to authenticated user via
path traversal. (CVE-2017-2595)

* HTTP Request smuggling vulnerability due to permitting invalid characters
in HTTP requests. (CVE-2017-2666)

* Websocket non clean close can cause IO thread to get stuck in a loop.
(CVE-2017-2670)

* Privilege escalation with security manager's reflective permissions when
granted to Hibernate Validator. (CVE-2017-7536)

* Potential http request smuggling as Undertow parses the http headers with
unusual whitespaces. (CVE-2017-7559)

* Properties based files of the management and the application realm are
world readable allowing access to users and roles information to all the
users logged in to the system. (CVE-2017-12167)

* RBAC configuration allows users with a Monitor role to view the sensitive
information. (CVE-2016-7061)

* Improper whitespace parsing leading to potential HTTP request smuggling.
(CVE-2017-12165)
