The Ubuntu security team deemed this advisory irrelevant for Ubuntu:16.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream tomcat7 package and not the tomcat7 package as distributed by Ubuntu.
The Tomcat package on Red Hat Enterprise Linux (RHEL) 7, Fedora, CentOS, Oracle Linux, and possibly other Linux distributions uses weak permissions for /usr/lib/tmpfiles.d/tomcat.conf, which allows local users to gain root privileges by leveraging membership in the tomcat group.
