SCA: security update for pyquorum (GHSA-7r92-3jgr-r65q)

medium Tenable Cloud Security Plugin ID 441352

Description

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

 - PyQuorum is a cryptographic library for secret sharing and key management. Prior to 0.2.1, the mul_mod
 function implements multiplication via a binary expansion loop whose execution time depends on the Hamming
 weight of the second operand (the exponent). An attacker who can measure the time of secret‑sharing
 operations (e.g., via a remote service) could progressively recover the values of shares, ultimately
 leading to secret reconstruction. This vulnerability is fixed in 0.2.1. (CVE-2026-44368)

Solution

Update the pyquorum library and its related packages to version 0.2.1 or later.
