Summary

An improper handing of overflow in the UTF-8 decoder with
supplementary characters can lead to an infinite loop in the decoder
causing a Denial of Service.

CVE-2018-8034

The host name verification when using TLS with the WebSocket client
was missing. It is now enabled by default.

For Debian 8 "Jessie", these problems have been fixed in version
8.0.14-1+deb8u13.

We recommend that you upgrade your tomcat8 packages.
