Astra Linux – Vulnerability in Nettle

A flaw was discovered in Nettle versions prior to 3.7.2. In these versions, several Nettle signature verification functions—GOST DSA, EDDSA, and ECDSA—result in the Elliptic Curve Cryptography point ECC’s multiply function being called with out-of-range scalers. This may lead to incorrect results...

Astra Linux – Vulnerability in Node-Elliptic

The Elliptic package 6.5.7 for Node.js, in its ECDSA implementation, does not correctly verify valid signatures when the hash contains at least four leading 0 bytes, and when the order of the elliptic curve’s base point is smaller than the hash, due to an truncateToN anomaly. This results in vali...

Astra Linux – Vulnerability in python-pysaml2

PySAML2 is a pure Python implementation of the SAML Version 2 Standard. Before version 6.5.0, PySAML2 had a flaw in the verification of cryptographic signatures. This issue affects users of pysaml2 who use the default CryptoBackendXmlSec1 backend and need to verify signed SAML documents. PySAML2...
