CWE-328  (opens in a new tab)

How to fix?

Upgrade cryptography to version 42.0.2 or higher.

Overview

Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to an issue in the POLY1305 MAC implementation on PowerPC CPUs. An attacker can corrupt the application state and cause incorrect calculations or potential denial of service by influencing the use of the POLY1305 MAC algorithm.

Note:

This is only exploitable if the attacker has the ability to affect the algorithm's usage and the application relies on non-volatile XMM registers.
