    "GHSA-g9mp-8g3h-3c5c"
  ],
  "details": "The Noise protocol implementation suffers from weakened\ncryptographic security after encrypting 2^64 messages, and a\npotential denial of service attack.\n\nAfter 2^64 (~18.4 quintillion) messages are encrypted with the\nEncrypt function, the nonce counter will wrap around, causing\nmultiple messages to be encrypted with the same key and nonce.\n\nIn a separate issue, the Decrypt function increments the nonce\nstate even when it fails to decrypt a message. If an attacker\ncan provide an invalid input to the Decrypt function, this will\ncause the nonce state to desynchronize between the peers,\nresulting in a failure to encrypt all subsequent messages.\n",
