The remote host is missing an update for the Debian 'tomcat7' package(s) announced via the DSA-3721-1 advisory. Multiple security vulnerabilities have been discovered in the Tomcat servlet and JSP engine, which may result in possible timing attacks to determine valid user names, bypass of the SecurityManager, disclosure of system properties, unrestricted access to global resources, arbitrary file overwrites, and potentially escalation of privileges. We recommend that you upgrade your tomcat7 packages
