Well, the password hash could be safely sitting in an LDAP server somewhere.
The bigger issue is that the server that you're sudo-ing on gets your
password in plaintext that could be snooped by a clever enough attacker
with access to your pty or if they have superuser you've really lost
because it would be even easier to get your password in plaintext by
replacing the sudo binary or screwing with PAM.
