[Security] Bump ws from 7.4.3 to 7.5.2

[dependabot-preview[bot]]

Bumps ws from 7.4.3 to 7.5.2. 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.

7.5.2

Bug fixes

• The opening handshake is now aborted if the client receives a Sec-WebSocket-Extensions header but no extension was requested or if the server indicates an extension not requested by the client (aca94c86).

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.
