"The version of Tomcat installed on the remote host is prior to 9.0.16.
It is, therefore, affected by a vulnerability as referenced in the
fixed_in_apache_tomcat_9.0.16_security-9 advisory.

  - The HTTP/2 implementation accepted streams with
    excessive numbers of SETTINGS frames and also permitted
    clients to keep streams open without reading/writing
    request/response data. By keeping streams open for
    requests that utilised the Servlet API's blocking I/O,
    clients were able to cause server-side threads to block
    eventually leading to thread exhaustion and a DoS.
    (CVE-2019-0199)

Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
