Re: mountd remote exploit?

[morex () NIRVANA NET (morex .-)]

To my knowledge there are 3 different versions of the mountd remote
exploit going around. I found a bin on my shell server from a user and ran
it on a outdated box of my own and it did work. I have not seen the
source.. only thing bin. So I  do know there is a remote exploit going
around.
