suid doesn't work

[prl at eiger.uucp]

But DON'T actually do this [[ setuid shells ]] if you want to keep your
system in any way secure. There is a kernel bug (in all Unixes with the #!
feature, not just SunOS) which allows set-uid shell scripts to be tricked
into allowing *any* commands to be executed setuid in place of the shell
script!!

	DON'T DO IT!! See Maarten Litmaath's posting in
	comp.sources.misc v05i097 for a probably secure way
	of doing what you want.

I am surprised that wnl didn't warn about this problem.

[[ Wnl didn't warn about this problem because wnl wasn't aware of it.
Unfortunately, I don't have the time to ingest all the information (and
weed out the noise) that the net produces.  Thank you for bringing it to
everyone's attention.  --wnl ]]
