SCA: security update for github.com/flynn/noise (GHSA-6cr6-fmvc-vw2p)

high Tenable Self-Hosted Container Security Plugin ID 411381

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2021-4239)
