ssh: return an error for malformed ed25519 public keys rather than panic An attacker can craft an ssh-ed25519 or sk-ssh-ed25519@openssh.com public key, such that the library will panic when trying to verify a signature with it. Clients can deliver such a public key and signature to any golang.org/x/crypto/ssh server with a PublicKeyCallback, and servers can deliver them to any golang.org/x/crypto/ssh client. This issue was discovered and reported by Alex Gaynor, Fish in a Barrel, and is tracked as CVE-2020-9283.
