Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3723-1 advisory.

 It was discovered that Tomcat incorrectly handled decoding certain UTF-8 strings. A remote attacker could possibly use this issue to cause Tomcat to crash, resulting in a denial of service. (CVE-2018-1336)

 It was discovered that the Tomcat WebSocket client incorrectly performed hostname verification. A remote attacker could possibly use this issue to intercept sensitive information. (CVE-2018-8034)
