Emacs 21.2 can't be compressed into 30008 bytes.  No fscking way.  The
most likely explanation is that this machine has been hacked, emacs (and
likely other binaries) replaced by a propagating virus that does its
damage code, then fetches and executes the original command from
somewhere else.

Try a general ls -l /usr/bin and see what other setuid root binaries you
got.

Another explanation would be that emacs has been replaced by emacsclient
that is setuid because of a hack or braindamage.
