security issues, various bugs, and add several enhancements are now
available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team has rated this update as having low

JBoss Enterprise Application Platform is a platform for Java applications,
which integrates the JBoss Application Server with JBoss Hibernate and
JBoss Seam. OpenID4Java allows you to implement OpenID authentication in
your Java applications. OpenID4Java is a Technology Preview.
This JBoss Enterprise Application Platform 5.1.2 release for Red Hat
Enterprise Linux 6 serves as a replacement for JBoss Enterprise Application
Platform 5.1.1.
These updated packages include bug fixes and enhancements. Refer 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 issues are also fixed with this release:
It was found that the invoker servlets, deployed by default via
httpha-invoker, only performed access control on the HTTP GET and POST
methods, allowing remote attackers to make unauthenticated requests by
using different HTTP methods. Due to the second layer of authentication
provided by a security interceptor, this issue is not exploitable on
default installations unless an administrator has misconfigured the
security interceptor or disabled it. (CVE-2011-4085)
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/server/[PROFILE]/deploy/" directory and any other customized
configuration files of your JBoss Enterprise Application Platform.
All users of JBoss Enterprise Application Platform 5.1.1 on Red Hat
Enterprise Linux 6 are advised to upgrade to these updated packages. The
JBoss server process must be restarted for the update to take effect.
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
