(RHSA-2015:2537) Critical: Red Hat JBoss Portal 6.2.0 commons-collections security update

Red Hat JBoss Portal is the open source implementation of the Java EE suite
of services and Portal services running atop Red Hat JBoss Enterprise
Application Platform.

It was found that the Apache commons-collections library permitted code
execution when deserializing objects involving a specially constructed
chain of classes. A remote attacker could use this flaw to execute
arbitrary code with the permissions of the application using the
commons-collections library. (CVE-2015-7501)
