A popular method is to create a buffer overflow
that results in root access.

Yes, but you would need to run it from from inetd
(which is the normal way of running a telnet server).

They don't know it's dialed-in.  They simply see an
open telnet server and jump on it.  As I said before,
their rootkit is unlikely to work on BL3.  But the
attempt to install it might hose your filesystem.

It takes very little time to install a rootkit 
(the purpose of which is to conceal all signs of 
the invader).  If the installation is successful,
you will probably notice nothing.

Did you look for sed in MANIFEST.gz ?
