Re: Possible Linuxconf Vulnerability

[desync () nwlink com (Desync)]

Where do you draw the line between poor system managment and exploitable
programs. If I set suid root on /bin/bash, is that to say its an
exploit?

Obviously, someone would have to remove clock for this to occur. Which
would conclude that either A) you had incorrect permissions for clock B)
they had allready used some means of another true exploit to cause other
program to misbehave.

If someone really wanted to do some damage with physical access to a
machine, popping a rescue disk set into the drive and rebooting with the
reset switch would do fine.
