How to fix?

There is no fixed version for Debian:9 golang-1.8.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-1.8 package and not the golang-1.8 package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

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.
