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.
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).
