Description

Red Hat JBoss Enterprise Web Platform is a platform for Java applications,
which integrates the JBoss Web Server with JBoss Hibernate and JBoss Seam.

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 Web Platform 5.2.0 on Red Hat
Enterprise Linux 4, 5, and 6 are advised to upgrade to these updated
packages. The JBoss server process must be restarted for the update to take
effect.
