Of course, this only works if you exist in the sudoers file, which
makes it pretty benign.  I agree that sudo should ask for a password
and this is fixed in sudo 1.5.4p1, available now from:

It is still possible for a user in sudoers to probe for binaries
but it's not really possible to disable that without making it
impossible for a sudo user to know *which* version of a command
was disallowed (for instance, sudoers may specify the system "ls"
and the user may have the GNU version first in their path).
