    Summary: Misleading message verification in golang.org/x/crypto/openpgp/clearsign

    Details: The clearsign package accepts some malformed messages, making it possible for an attacker to trick a human user (but not a Go program) into thinking unverified text is part of the message. With fix, messages with malformed headers in the SIGNED MESSAGE section are rejected.
