1. Summary:

An update is now available for Red Hat JBoss Enterprise Application
Platform.

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. Description:

Red Hat JBoss Enterprise Application Platform is a platform for Java
applications based on the JBoss Application Server.

This release of Red Hat JBoss Enterprise Application Platform 7.1.0 serves
as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.0,
and includes bug fixes and enhancements, which are documented in the
Release Notes document linked to in the References.

Security Fix(es):

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

* World executable permission on bin/jboss-cli after installation. Any
users of the system could cause harm, or shutdown the running instance.
(CVE-2016-7066)

* 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)
