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 4 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 4 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
