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-Protocolheader 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=sizeand/or themaxHeaderSizeoptions.7.4.5
Bug fixes
- UTF-8 validation is now done even if
utf-8-validateis not installed (23ba6b29).- Fixed an edge case where
websocket.close()andwebsocket.terminate()did not close the connection (67e25ff5).
