Statement: Oracle OpenSSO is provided as part of the opensso quickstart example application shipped with JBoss Enterprise SOA Platform 5. The CVE-2011-3506, CVE-2011-3517, and CVE-2012-0079 flaws are not exposed unless the opensso quickstart example application is deployed, or you have created and deployed a custom application that is packaged with a copy of Oracle OpenSSO as provided by the opensso quickstart. The opensso quickstart has been removed in JBoss Enterprise SOA Platform 5.3.0 to address these flaws. Users interested in continuing to receive updates for their custom applications using Oracle OpenSSO are advised to contact Oracle as Red Hat is no longer supporting OpenSSO.
This issue has been addressed in following products: JBoss Enterprise SOA Platform 5.3.0 Via RHSA-2012:1125 https://rhn.redhat.com/errata/RHSA-2012-1125.html
