3. Description:

Apache Xerces for Java (Xerces-J) is a high performance, standards
compliant, validating XML parser written in Java. The xerces-j2 packages
provide Xerces-J version 2.

A resource consumption issue was found in the way Xerces-J handled XML
declarations. A remote attacker could use an XML document with a specially
crafted declaration using a long pseudo-attribute name that, when parsed by
an application using Xerces-J, would cause that application to use an
excessive amount of CPU. (CVE-2013-4002)

All xerces-j2 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. Applications using the
Xerces-J must be restarted for this update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
