Secure setuid shell scripts

[Martin Foord]

I have only started to read this section in the last few days but have read
much on the subject of set[ug]id shell scripts. Probably due to my
ignorance I haven't been able to pick up the main threads of the
problems that occur with them. Could somone elighten me as to the
security hole with set[ug]id scripts and `#!' and the problem with
symbolic links.
				Many Thanks in Advance,
						Martin Foord.
