Looking for some clarification on HTTP Stack Update for NetWare 6.5 SP5 - TID2973698

On:
http://support.novell.com/cgi-bin/se...i?/2973698.htm

it states that: "Novell has addressed a server abend issue related to HTTPSTK.NLM in NetWare 6.5 Support Pack 5."

Question: Does that mean only SP5 and not anything prior? We are currently running NWSP3.....

TIA!......
