base score, which gives a detailed severity rating, is available from the
CVE link in the References section.

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.
