"Two security issues have been discovered in the Tomcat servlet and JSP
engine.

CVE-2018-1336

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.

NOTE: Tenable Network Security has extracted the preceding description
block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
