Red Hat Security Advisory 2014-0590-01 - JBoss Enterprise Application Platform is a platform for Java applications, which integrates the JBoss Application Server with JBoss Hibernate and JBoss Seam. 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 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.

Synopsis: Important: Red Hat JBoss Enterprise Application Platform 5.2.0 security update
Advisory ID: RHSA-2014:0590-01
Product: Red Hat JBoss Enterprise Application Platform
Advisory URL: https://rhn.redhat.com/errata/RHSA-2014-0590.html
Issue date: 2014-06-02

=====================================================================

1. Summary:

An update for JBoss Enterprise Application Platform 5.2.0, which fixes one
security issue and one bug, is now available from the Red Hat Customer
Portal.

The Red Hat Security Response Team has rated this update as having
Important security impact. A Common Vulnerability Scoring System (CVSS)
base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

2. Description:

JBoss Enterprise Application Platform is a platform for Java applications,
which integrates the JBoss Application Server with JBoss Hibernate and
JBoss Seam.

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)

This update also fixes the following bug:

It was observed that when using the Transfomer to convert a StreamSource to
DOMResult, the performance of the conversion degraded as the size of the
character data increased. For example, converting a 50 MB XML BLOB would
take a very long time to finish. This issue has been resolved in this
release by adjusting both the SAX2DOM and DOMBuilder classes to handle
larger inputs more efficiently. (JBPAPP-10991)

All users of JBoss Enterprise Application Platform 5.2.0 as provided from
the Red Hat Customer Portal are advised to apply this update. The JBoss
server process must be restarted for this update to take effect.

3. Solution:

The References section of this erratum contains a download link (you must
log in to download the update). Before applying the update, back up your
existing JBoss Enterprise Application Platform installation (including all
applications and configuration files).

4. Bugs fixed (https://bugzilla.redhat.com/):
