Summary
Red Hat Security Advisory: JBoss Enterprise BRMS Platform 5.2.0 update

Notes

Topic
JBoss Enterprise BRMS Platform 5.2.0 roll up patch 1, which fixes two security issues, various bugs, and adds enhancements, is now available from the Red Hat Customer Portal. The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.
Details
JBoss Enterprise BRMS Platform 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 JBoss Enterprise BRMS Platform 5.2.0. It includes various bug fixes and enhancements. The following security issues are also fixed with this release: It was found that RESTEasy was vulnerable to XML External Entity (XXE) attacks. If a remote attacker submitted a request containing an external XML entity to a RESTEasy endpoint, the entity would be resolved, allowing the attacker to read files accessible to the user running the application server. This flaw affected DOM (Document Object Model) Document and JAXB (Java Architecture for XML Binding) input. (CVE-2012-0818) It was found that the Attribute Exchange (AX) extension of OpenID4Java was not checking to ensure attributes were signed. If AX was being used to receive information that an application only trusts the identity provider to assert, a remote attacker could use this flaw to conduct man-in-the-middle attacks and compromise the integrity of the information via a specially-crafted request. By default, only the JBoss Seam openid example application uses OpenID4Java. (CVE-2011-4314) Warning: Before applying the update, back up your existing JBoss Enterprise BRMS Platform installation (including its databases, applications, configuration files, and so on). All users of JBoss Enterprise BRMS Platform 5.2.0 as provided from the Red Hat Customer Portal are advised to apply this roll up patch.
