github.com/golang/crypto is vulnerable to signature verification with malformed public keys. The vulnerability exists because it does not handle malformed ed25519 public keys properly, allowing a malicious SSH client to provide malicious a ssh-ed25519 or [email protected] public keys to panic any SSH servers with PublicKeyCallback during signature verification. SSH servers can also deliver such keys to any golang.org/x/crypto/ssh clients.
