Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

When running an untrusted application under a SecurityManager it was possible, under some circumstances, for that application to retain references to the request or response objects and thereby access and/or modify information associated with another web application.
