Uhm... This doesn't really affect servers since they don't run code provided by unsecure sources. Unless of course you have a bunch of programmers SSHing into it for some crazy reason.
IE if you have a bunch of servers you don't have to rush to patch since all the exectuable code is provided by you.
Only executable code can cause the overrun in root, The only way to break in would be to use another exploit first to gain control of an existing user mode process and then gain root. As long as all your user mode processes are secure your good to go.
If you don't trust your user mode processes....
