greetings,
i have done a litte reseach on a SuSE linux 9.0 box
for possible symlink attacks. i have checked nearly
every script i could found on the system. i havent
found much and nothing very special.i dont have a
clue if the following scripts are somewhere on the
system executed but maybe someone useses them in a
script or something like that.
