[Security] Bump ws from 7.2.5 to 7.5.1

[dependabot-preview[bot]]

Bumps ws from 7.2.5 to 7.5.1. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

ReDoS in Sec-Websocket-Protocol header

Impact

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

Proof of concept

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);
}

Release notes

Sourced from ws's releases.

7.5.1

Bug fixes

• Fixed an issue that prevented the connection from being closed properly if an error occurred simultaneously on both peers (b434b9f1).

7.5.0

Features

• Some errors now have a code property describing the specific type of error that has occurred (#1901).

Bug fixes

• A close frame is now sent to the remote peer if an error (such as a data framing error) occurs (8806aa9a).
• The close code is now always 1006 if no close frame is received, even if the connection is closed due to an error (8806aa9a).

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.
