SSH 4.3 dos question

["Francois Yang" <francois.y@gmail.com>]

I'm evaluating a friends server and I noticed that he had a vulnerable
version of SSH.
Nmap result;
22/tcp open  ssh     OpenSSH 4.3 (protocol 1.99)

According to security focus it is vulnerable to a DOS attack.
http://www.securityfocus.com/bid/20216/info
cve - CVE-2006-4924

When I run the script from millw0rm which is suppose to cause the DOS
nothing happens.
The scripts runs fine saying that it worked, but the server doesn't
seem to be affected.

Any ideas?

thanks.
