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 fix for CVE-2012-0818 was incomplete: external
parameter entities were not disabled when the
resteasy.document.expand.entity.references parameter was set to false.
A remote attacker able to send XML requests to a RESTEasy endpoint could
use this flaw to read files accessible to the user running the application
server, and potentially perform other more advanced XXE attacks.
(CVE-2014-3490)

This issue was discovered by David Jorm of Red Hat Product Security.

All users of Red Hat JBoss Enterprise Application Platform 6.3.0 on Red Hat
Enterprise Linux 5, 6, and 7 are advised to upgrade to these updated
packages. The JBoss server process must be restarted for the update to
take effect.

Solution

Before applying this update, make sure all previously released errata
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
updated. The updated version of such files will be stored as the rpmnew
files. Make sure to locate any such files after the update and merge any
changes manually.
