That's correct. It appears that the Oracle installation leaves the tcl/oratcl shell as setuid 'root', executable by anyone. The same security hole would exists if /bin/sh was copied to ../bin/supersh and permissions set as rws-r-x-r-x and owner root.

I agree with Bob in many cases, but I also like to point to a quote (who's author I don't remember at the moment:

	Don't attribute to malice what can more easily be 
	explained by stupidity (or carelessness).

(Which suggests this quote represents the Occam's Razor of security?)
