[sudo-users] Keep LD_LIBRAY_PATH

I second that request for the technique that would allow a non-privileged
user to get a root prompt using the listed shell script.

I am not asking that because I don't think it could possibly exist, I am
asking that because this is a common technique and if someone knows of a
vunerability to this, I would really like to know.

A previous listed mentioned that they were not allowed to use wrapper
scripts because their security people had a strict rule.  However they were
allowed to put rules in sudoers that were suspect: (ALL,!root).

One improvement that could be made to sudo that would make it more secure
regarding shell scripts is if sudo confirmed that the shell script's owner
and mode are secure. e.g. if a shell script is being invoked as root, it's
owner should be root, and mode should be 700. (actually, I think the rules
should be a little more complex, but I think that gives you an idea of what
I would want).
