openjdk: Improve certification checking (Oracle CPU 2026-07)
A flaw was found in OpenJDK. OpenJDK can apply two different security meanings to the same wildcard dNSName SAN across certificate policy enforcement and hostname verification. During path validation, DNSName.constrains compares .foo.com and secret.foo.com literally and returns NAMESAMETYPE, so...
Improper Certificate Validation
Overview Affected versions of this package are vulnerable to Improper Certificate Validation in the DNSConstraint::matches. An attacker can bypass name constraints by presenting a certificate with a wildcard DNS Subject Alternative Name that is improperly validated, allowing acceptance of...
python-cryptography verifier accepts wildcard DNS names allowing escape from permittedSubtrees
Summary If an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com, python-cryptography's verifier accepts which allows escaping outside of the permitted names. PoC !/usr/bin/env python3 """Standalone PoC: pyca's...
