Description

Red Hat JBoss BRMS is a business rules management system for the
management, storage, creation, modification, and deployment of JBoss Rules.

This roll up patch serves as a cumulative upgrade for Red Hat JBoss BRMS
5.3.1. It includes various bug fixes. The following security issues are
also fixed with this release:

It was found that XStream could deserialize arbitrary user-supplied XML
content, representing objects of any type. A remote attacker able to pass
XML to XStream could use this flaw to perform a variety of attacks,
including remote code execution in the context of the server running the
XStream application. (CVE-2013-7285)

It was found that the secure processing feature of Xalan-Java had
insufficient restrictions defined for certain properties and features.
A remote attacker able to provide Extensible Stylesheet Language
Transformations (XSLT) content to be processed by an application using
Xalan-Java could use this flaw to bypass the intended constraints of the
secure processing feature. Depending on the components available in the
classpath, this could lead to arbitrary remote code execution in the
context of the application server running the application that uses
Xalan-Java. (CVE-2014-0107)

All users of Red Hat JBoss BRMS 5.3.1 as provided from the Red Hat Customer
Portal are advised to apply this roll up patch.
