=====================================================================

1. Summary:

JBoss Enterprise Portal Platform 5.2.1, which fixes two security issues
and various bugs, is now available from the Red Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having moderate
security impact. Common Vulnerability Scoring System (CVSS) base scores,
which give detailed severity ratings, are available for each vulnerability
from the CVE links in the References section.

2. Description:

JBoss Enterprise Portal Platform is the open source implementation of the
Java EE suite of services and Portal services running atop JBoss Enterprise
Application Platform. It comprises a set of offerings for enterprise
customers who are looking for pre-configured profiles of JBoss Enterprise
Middleware components that have been tested and certified together to
provide an integrated experience.

This release of JBoss Enterprise Portal Platform 5.2.1 serves as a
replacement for JBoss Enterprise Portal Platform 5.2.0, and includes bug
fixes. Refer to the JBoss Enterprise Portal Platform 5.2.1 Release Notes
for information on the most significant of these changes. The Release Notes
will be available shortly from
https://docs.redhat.com/docs/en-US/index.html

The following security issues are also fixed with this release:

It was found that RESTEasy was vulnerable to XML External Entity (XXE)
attacks. If a remote attacker submitted a request containing an external
XML entity to a RESTEasy endpoint, the entity would be resolved, allowing
the attacker to read files accessible to the user running the application
server. This flaw affected DOM (Document Object Model) Document and JAXB
(Java Architecture for XML Binding) input. (CVE-2012-0818)

It was found that the Attribute Exchange (AX) extension of OpenID4Java was
not checking to ensure attributes were signed. If AX was being used to
receive information that an application only trusts the identity provider
to assert, a remote attacker could use this flaw to conduct
man-in-the-middle attacks and compromise the integrity of the information
via a specially-crafted request. By default, only the JBoss Seam openid
example application uses OpenID4Java. (CVE-2011-4314)

Warning: Before applying this update, back up all applications deployed on
JBoss Enterprise Portal Platform, along with all customized configuration
files.

All users of JBoss Enterprise Portal Platform 5.2.0 as provided from the
Red Hat Customer Portal are advised to upgrade to JBoss Enterprise Portal
Platform 5.2.1.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). Before applying the update, back up all
applications deployed on JBoss Enterprise Portal Platform, along with all
customized configuration files.

4. Bugs fixed (http://bugzilla.redhat.com/):
