I tend to agree on the $SUDO_USER var and I understand your script example
is indeed a rough example. But make sure you include the full path in your
wrapper. If I were up to no-good I might do something like:
set path ($home/bin $path)
then drop my own passwd command in my $home/path directory.

For some reason I thought sudo would ensure that whenever sudo was run
it was run with the correct SUDO_USER environment variable with env_reset.
If I wrote a simple script like:
set the permissions to 700 (root:root)
USERS ALL=(ALL) /bin/change_password
The script would be run like
$ sudo /bin/change_password
How can the user change the SUDO_USER environment variable?
Not arguing your facts, just saying I don't understand.
