Astra Linux - уязвимость в libdata-validate-ip-perl

The Data::Validate::IP module in Perl version 0.29 does not properly handle extra zero characters at the beginning of an IP address string. In some cases, this allows attackers to bypass access controls that are based on IP addresses...

Astra Linux - уязвимость в 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...
