    CVE-2021-4239 (GCVE-0-2021-4239)

    Vulnerability from nvd – Published: 2022-12-27 21:13 – Updated: 2025-04-14 16:59
    VLAI
    Title
    Weak encryption and denial of service in github.com/flynn/noise
    Summary
    The Noise protocol implementation suffers from weakened cryptographic security after encrypting 2^64 messages, and a potential denial of service attack. 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.
