dependabot[bot] commented 3 years ago

Bumps ws from 7.4.5 to 7.4.6.

Release notes

Sourced from ws's releases.

7.4.6

Bug fixes

  • Fixed a ReDoS vulnerability (00c425ec).

A specially crafted value of the Sec-Websocket-Protocol header could be used to significantly slow down a ws server.

for (const length of [1000, 2000, 4000, 8000, 16000, 32000]) {
  const value = 'b' + ' '.repeat(length) + 'x';
  const start = process.hrtime.bigint();

value.trim().split(/ *, */);


const end = process.hrtime.bigint();


console.log('length = %d, time = %f ns', length, end - start);
}

The vulnerability was responsibly disclosed along with a fix in private by Robert McLaughlin from University of California, Santa Barbara.

In vulnerable versions of ws, the issue can be mitigated by reducing the maximum allowed length of the request headers using the --max-http-header-size=size and/or the maxHeaderSize options.

Looks like ws is up-to-date now, so this is no longer needed.
