    Summary: Unauthenticated Nonce Increment in snow

    Details: There was a logic bug where unauthenticated payloads could still cause a nonce increment in snow's internal state. For an attacker with privileges to inject packets into the channel over which the Noise session operates, this could allow a denial-of-service attack which could prevent message delivery by sending garbage data. Note that this only affects those who are using the stateful TransportState, not those using StatelessTransportState. This has been patched in version 0.9.5, and all users are recommended to update.
