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

For Debian 8 ‘Jessie’, this problem has been fixed in version 7.0.56-3+really7.0.90-1.

We recommend that you upgrade your tomcat7 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.
