"Updated xerces-j2 packages that fix one security issue are now
available for Red Hat Enterprise Linux 6 and 7.

Red Hat Product Security has rated this update as having Moderate
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.

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."
