"From Red Hat Security Advisory 2014:1034 :

Updated tomcat packages that fix one security issue are now available
for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having Low 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 Tomcat is a servlet container for the Java Servlet and
JavaServer Pages (JSP) technologies.

It was found that, in certain circumstances, it was possible for a
malicious web application to replace the XML parsers used by Apache
Tomcat to process XSLTs for the default servlet, JSP documents, tag
library descriptors (TLDs), and tag plug-in configuration files. The
injected XML parser(s) could then bypass the limits imposed on XML
external entities and/or gain access to the XML files processed for
other web applications deployed on the same Apache Tomcat instance.
(CVE-2014-0119)

All Tomcat users are advised to upgrade to these updated packages,
which contain a backported patch to correct this issue. Tomcat must be
restarted for this update to take effect."
