(RHSA-2011:1803) Low: JBoss Enterprise Web Platform 5.1.2 update

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 for Red Hat Enterprise
Linux 5 serves as a replacement for JBoss Enterprise Web Platform 5.1.1.

These updated packages include 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 on Red Hat Enterprise
Linux 5 are advised to upgrade to these updated packages. The JBoss server
process must be restarted for the update to take effect.
