Description

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

The following security issue is addressed with this release:

It was found that the Java Standard Tag Library (JSTL) allowed the processing of untrusted XML documents to utilize external entity references, which could access resources on the host system and, potentially, allowing arbitrary code execution. (CVE-2015-0254)

Note: Tag Library users may need to take additional steps after applying this update. Detailed instructions on the additional steps can be found here: https://access.redhat.com/solutions/1584363

Red Hat would like to thank David Jorm of IIX, and the Apache Software Foundation for reporting the CVE-2015-0254 flaw.

This release serves as a replacement for Red Hat JBoss Enterprise Application Platform 6.4.5, and includes bug fixes and enhancements. Documentation for these changes will be available shortly from the Red Hat JBoss Enterprise Application Platform 6.4.6 Release Notes, linked to in the References.

All users of Red Hat JBoss Enterprise Application Platform 6.4 on Red Hat Enterprise Linux 5 are advised to upgrade to these updated packages. The JBoss server process must be restarted for the update to take effect.
