tomcat8 - security update

Multiple security vulnerabilities have been discovered in the Tomcat
servlet and JSP engine, which may result in information disclosure, the
bypass of CSRF protections, bypass of the SecurityManager or denial of
service.

For the stable distribution (jessie), these problems have been fixed in
version 8.0.14-1+deb8u2.

For the unstable distribution (sid), these problems have been fixed in
version 8.0.36-1.

We recommend that you upgrade your tomcat8 packages.
