How to fix?

Upgrade github.com/katzenpost/noise to version 0.0.3 or higher.

Overview

github.com/katzenpost/noise is a Noise Protocol Framework: Katzenpost fork of the flynn noise library.

Affected versions of this package are vulnerable to Integer Overflow or Wraparound. If 2^64 (~18.4 quintillion) or more messages are encrypted with Encrypt after handshaking, the nonce counter will wrap around, causing multiple messages to be encrypted with the same key and nonce, resulting in a potentially catastrophic weakening of the security properties of the symmetric cipher.
