As Josh make me notice i' m partial in error.
The problem was that i' ve installed kernel 2.4.5 on my box after
(Slakware 7.0 come with kernel 2.2.13) , so I gave make modules_install at
the end of the compilation :
if [ -r System.map ]; then /sbin/depmod -ae -F System.map 2.4.5; fi
At the end depmod -a is called and it creates modules.dep, and it gives
"-rw-r--r--" permissions.
The Slakware startup script calls depmod -a, but modules.dep isn't erased
before, but just "updated", so it keeps "-rw-r--r--" permissions.
I' ve tried erasing modules.dep and then rebooting and modules.dep, this
time beeing created, has , as Josh, said "-rw-rw-rw" permissions.
So in the end this exploit will work only if the kernel hasn't benn
recompiled with make modules_install (or depmod -a called otherwise
not at the startup) of if modules.dep is erased before "depmod
-a" at the startup (Slakware 7.0 init script doesn' t do that, so it is
not vulnerable :) )
I' m sorry for my partially erroneus post
