Two vulnerabilities were discovered in tomcat7, a servlet and JSP engine.
CVE-2017-5647 Pipelined requests were processed incorrectly, which could result in some responses appearing to be sent for the wrong request.
CVE-2017-5648 Some application listeners calls were issued against the wrong objects, allowing untrusted applications running under a SecurityManager to bypass that protection mechanism and access or modify information associated with other web applications.
