chore(deps): [security] bump ws from 7.4.2 to 7.4.6 #110

Closed dependabot-preview[bot] closed 3 years ago

dependabot-preview[bot] commented 3 years ago

Bumps ws from 7.4.2 to 7.4.6. 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); }

Patches

... (truncated)

Affected versions: >= 5.0.0 < 7.4.6

Release notes

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.

7.4.5

Bug fixes

  • UTF-8 validation is now done even if utf-8-validate is not installed (23ba6b29).
  • Fixed an edge case where websocket.close() and websocket.terminate() did not close the connection (67e25ff5).

7.4.4

Bug fixes

  • Fixed a bug that could cause the process to crash when using the permessage-deflate extension (92774377).

7.4.3

Bug fixes

  • The deflate/inflate stream is now reset instead of reinitialized when context takeover is disabled (#1840).
