Advisory ID:       RHSA-2011:1806-01
Product:           JBoss Enterprise Web Platform
Advisory URL:      https://rhn.redhat.com/errata/RHSA-2011-1806.html

CVE Names:         CVE-2011-4314 
=====================================================================

1. Summary:

JBoss Enterprise Web Platform 5.1.2, which fixes one security issue,
various bugs, and adds several enhancements is now available from the Red
Hat Customer Portal.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available from the CVE link in
the References section.

2. Description:

The Enterprise Web Platform is a slimmed down profile of the JBoss
Enterprise Application Platform intended for mid-size workloads with light
and rich Java applications. OpenID4Java allows you to implement OpenID
authentication in your Java applications. OpenID4Java is a Technology
Preview.

This JBoss Enterprise Web Platform 5.1.2 release serves as a replacement
for JBoss Enterprise Web Platform 5.1.1.

This update includes bug fixes and enhancements. JBoss Enterprise Web
Platform is a subset of JBoss Enterprise Application Platform. Users are
directed to the JBoss Enterprise Application Platform 5.1.2 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 issue is also fixed with this release:

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 the
"jboss-as-web/server/[PROFILE]/deploy/" directory and any other customized
configuration files of your JBoss Enterprise Web Platform.

All users of JBoss Enterprise Web Platform 5.1.1 as provided from the Red
Hat Customer Portal are advised to upgrade to JBoss Enterprise Web Platform
5.1.2.
