Description

Red Hat JBoss Enterprise Application Platform 6 is a platform for Java
applications based on JBoss Application Server 7.

It was found that the implementation of the
org.picketlink.common.util.DocumentUtil.getDocumentBuilderFactory() method
provided a DocumentBuilderFactory that would expand entity references.
A remote, unauthenticated attacker could use this flaw to read files
accessible to the user running the application server, and potentially
perform other more advanced XXE attacks. (CVE-2014-3530)

Red Hat would like to thank Alexander Papadakis for reporting this issue.

All users of Red Hat JBoss Enterprise Application Platform 6.2.4 on Red Hat
Enterprise Linux 5 and 6 are advised to upgrade to these updated packages.
The JBoss server process must be restarted for the update to take effect.

relevant to your system have been applied. Also, back up any customized Red
Hat JBoss Enterprise Application Platform 6 configuration files. On update,
the configuration files that have been locally modified will not be

files. Make sure to locate any such files after the update and merge any
changes manually.
