  script_tag(name:"insight", value:"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.

In addition this update further hardens Tomcat's init and maintainer scripts to prevent possible privilege escalations. Thanks to Paul Szabo for the report.

For Debian 7 Wheezy, these problems have been fixed in version 7.0.28-4+deb7u7.

We recommend that you upgrade your tomcat7 packages.
