    Denial of Service (DoS)

    websocket-driver is WebSocket protocol handler with pluggable I/O.

    Affected versions of this package are vulnerable to Denial of Service (DoS) attacks. The Buffer length is immediately allocated after reading the frame, up to a length that is no more that MAX_LENGTH, which is 2^53 - 1 (the largest precisely representable JS integer), and rejects larger frames with a 1009 error before creating the new Buffer. But Node buffers have a max length of 1GB (0x3fffffff). Parsing an incoming frame with length between 1GB and MAX_LENGTH, the parser will throw (and perhaps crash your whole server). Attackers can use this to their advantage and cause a Denial of Service on the servers.

    How to fix Denial of Service (DoS)?

    Upgrade websocket-driver to version 0.3.1 or higher.
