Red Hat JBoss Enterprise Application Platform is a platform for Java applications based on the JBoss Application Server. This release of Red Hat JBoss Enterprise Application Platform 7.0.9 serves as a replacement for Red Hat JBoss Enterprise Application Platform 7.0.8, and includes bug fixes and enhancements, which are documented in the Release Notes document linked to in the References. Security Fix: It was found that Apache Lucene would accept an object from an unauthenticated user that could be manipulated through subsequent post requests. An attacker could use this flaw to assemble an object that could permit execution of arbitrary code if the server enabled Apache Solr's Config API.
