No, not really. Unless you did something stupid in your configuration,
the password will be sent encrypted and can't be easily sniffed.
Public keys are better, however, since there you never send the key at all.

No, but in public accessible server will be compromise by
dictionary/brute force attacks.

If the user is able to dump the program he is root, and everything is open
anyway. dump is the least of your worries.
The purpose of ssh is to protect against eavesdropping from outside. It
does not protect at all from someone who has control of the machine it is
run on.

No, brute force only, and if the key is long enough (e.g. 1024-bit RSA)
then that is infeasible.
Dictionary is only appropriate when you have obtained a private key
encrypted with a password/phrase.

You missed the point. He's talking about password authentication, not
publickey.
