websocket-driver: Message corruption via abuse of protocol length headers

Severity:
High

Description

The frame format in draft versions of the WebSocket protocol includes a length header that allows an arbitrarily large integer to be encoded as a sequence of bytes with the high bit set. By sending an indefinite sequence of bytes with values 0x80 or above, a client can make the server parse these bytes into an ever-growing integer.

Recommendation

Update the websocket-driver package to the latest compatible version. Followings are version details:
