After 2^64 (~18.4 quintillion) messages are encrypted with the Encrypt function, the nonce counter will wrap around, causing multiple messages to be encrypted with the same key and nonce. In a separate issue, the Decrypt function increments the nonce state even when it fails to decrypt a message. If an attacker can provide an invalid input to the Decrypt function, this will cause the nonce state to desynchronize between the peers, resulting in a failure to encrypt all subsequent messages."},{"lang":"es","value":"La implementación del protocolo Noise sufre de seguridad criptográfica debilitada después de cifrar 2^64 mensajes y un posible ataque de denegación de servicio. Después de cifrar 2^64 (~18,4 quintillones) de mensajes con la función Encrypt , el contador nonce se ajustará, lo que provocará que se cifren varios mensajes con la misma clave y nonce. En un tema aparte, la función Decrypt incrementa el estado nonce incluso cuando no logra descifrar un mensaje.
