Hi there

Still digging in the howtos I eventually came to a quick guide on files 
security, especially regarding the set uid.

Doing a 
root# find /usr -type f  -perm +6000 -ls
gives me a freaking list of binaries.

When I read that Buffer overflows are 50 % (realistic ???) the cause of 
providing a root shell, well.... I am a little concerned.

Now  I can always modify some permissions but what is the risk of locking up 
the system for good ????
Any advice on the minimum of these files I should leave or remove?

Thanks 
Edouard
