supersuer by a normal user with chmod

[Raffaele Sandrini <maturarbeit@gmx.ch>]

Hi

On normal homedirs the owner of the files is the owner of the homedir. That
means he/she can alter the file permissions in the files he/she ownes (with
chmod)

I tested the following: As a normal user i crated a file in my homedir.
% touch test

I changed it to a exec file.
% chmod 700 test

No i set the superuser bit
% chmod +s test

It worked(!!!!!). That means that a user can download for example a BASH
binary and set the superuser bit for it ans has root privileges ??!!

Am i missing here something?

cheers,
Raffaele
