Amazon Linux 2023 : gnutls, gnutls-c++, gnutls-dane (ALAS2023-2026-1808)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1808 advisory. Permitted name constraints were wrongfully ignored when prior CAs only had excluded name constraints, resulting in a name constraint bypass. The issue was reported in the issue tracker as 1824...

CVE-2026-42011

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

CVE-2026-34073

A flaw was found in the cryptography library. This vulnerability occurs because DNS Domain Name System name constraints were not properly validated against the "peer name" during certificate validation, only against Subject Alternative Names SANs within child certificates. This oversight could...

Unity Linux 20.1070e Security Update: nodejs (UTSA-2025-680625)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-680625 advisory. Accepting arbitrary Subject Alternative Name SAN types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained...

AZL-8840 CVE-2021-44531 affecting package nodejs for versions less than 16.14.0-1

Accepting arbitrary Subject Alternative Name SAN types, unless a PKI is specifically defined to use a particular SAN type, can result in bypassing name-constrained intermediates. Node.js 12.22.9, 14.18.3, 16.13.2, and 17.3.1 was accepting URI SAN types, which PKIs are often not defined to use...
