Overview
Affected versions of this package are vulnerable to NULL Pointer Dereference via the websocket_reply_pong function in the gateway WebSocket transport. A malicious gateway can crash a FreeRDP-based client by sending a zero-length WebSocket ping, which causes the function to pass a null stream to the close-response handler and terminate the client process.
Workarounds
- Connect using
/gateway:transport:http,no-websocketsto avoid the WebSocket transport and its zero-length-ping crash path.
