Description
crypto/tls clients can panic when provided a certificate of the wrong type for the negotiated parameters. net/http clients performing HTTPS requests are also affected.
NVD description
The crypto/tls package of Go through 1.16.5 does not properly assert that the type of public key in an X.509 certificate matches the expected type when doing a RSA based key exchange, allowing a malicious TLS server to cause a TLS client to panic.
