Description :

From Red Hat Security Advisory 2017:1809 :

An update for tomcat is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Important. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)
