Security Vulnerabilities

tokio: reject_remote_clients Configuration corruption


On Windows, configuring a named pipe server with pipe_mode will force ServerOptions::reject_remote_clients as false.

This drops any intended explicit configuration for the reject_remote_clients that may have been set as true previously.

The default setting of reject_remote_clients is normally true meaning the default is also overridden as false.


Ensure that pipe_mode is set first after initializing a ServerOptions. For example:

let mut opts = ServerOptions::new();

quinn-proto: Denial of service in Quinn servers


Receiving QUIC frames containing a frame with unknown frame type could lead to a panic. Unfortunately this is issue was not found by our fuzzing infrastructure.

Thanks to the QUIC Tester research group for reporting this issue.
