go-micro before 6.0.0 Disabled TLS Certificate Verification via tls.Config Helper

go-micro before 6.0.0 contains an improper certificate validation vulnerability that allows network attackers to impersonate services because the shared TLS helper sets InsecureSkipVerify to true by default. Man-in-the-middle attackers can present any certificate to intercept or modify gRPC transport, HTTP and RabbitMQ broker, and Consul or etcd registry traffic, including authentication tokens and credentials.

The ECDSA operation of the micro-ecc library 1.0 is vulnerable to simple power analysis attacks which allows an adversary to extract the private ECC key.
