When verifying a certificate chain containing excluded DNS constraints, these constraints are not correctly applied to wildcard DNS SANs which use a different case than the constraint. This only affects validation of otherwise trusted certificate chains, issued by a root CA in the VerifyOptions.Roots CertPool, or in the system certificate pool.

Al verificar una cadena de certificados que contiene restricciones DNS excluidas, estas restricciones no se aplican correctamente a los SAN DNS comodín que utilizan mayúsculas/minúsculas diferentes a las de la restricción. Esto solo afecta la validación de cadenas de certificados que de otro modo serían de confianza, emitidas por una CA raíz en el CertPool VerifyOptions.Roots o en el grupo de certificados del sistema.
