Infinite Loop When Building Certificate Chains

[Tw1sm]

This function called when building certificate chains can (and will) enter an infinite loop, causing parsing to never finish

    @staticmethod
    def build_certificate_chain(start_ca_obj, all_ca_obj):
        chain = [start_ca_obj]
        current_ca = start_ca_obj

        while True:
            if current_ca.x509Certificate['subject'] == current_ca.x509Certificate['issuer']:
                # Found a self-signed certificate (root CA)
                break
            
            issuer_ca = ADDS.find_issuer_ca(start_ca_obj, all_ca_obj)
            if not issuer_ca:
                break
            chain.append(issuer_ca)
            current_ca = issuer_ca

        return [cert.Properties['certthumbprint'] for cert in chain]
