3. Description:

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

Security Fix(es):

* A vulnerability was discovered in the error page mechanism in Tomcat's
DefaultServlet implementation. A crafted HTTP request could cause undesired
side effects, possibly including the removal or replacement of the custom
error page. (CVE-2017-5664)

* A vulnerability was discovered in Tomcat. 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. (CVE-2017-5648)
