Well, on some Sun's I've been told that uuencode/decode is suid.
This is a silly, mindless thing to do (IMHO, of course :-).

With this, the directory that you are uudecoding into MUST be either
publically writable, or at least writable by the owner of the uudecode
program.


One thing that you could do is to put it in a private directory without
being setuid.  Ie:

% echo $PATH
/usr/jeff/.bin:/bin:/usr/bin:...

(Note that my private .bin is first in my path before the system's /bin)

cp /bin/uuencode ~/.bin/uuencode    (Do the same for uudecode)
chmod 755 ~/.bin/uuencode           (Do the same for uudecode)

Then, it should run as a normal program (hopefully)  If not, either
complain loudly to Sun, or go to uunet and get the BSD free'd version
and compile it.
