Does the RPC Attack affect Win 98?

Does the RPC attack affect Win 98?


M$ Security Bulletin:
http://www.microsoft.com/technet/sec.../MS08-067.mspx


The Bulletin states:

Customers who require custom support for older releases must
contact their Microsoft account team representative, their
Technical Account Manager, or the appropriate Microsoft partner
representative for custom support options

Does this mean M$ is still supporting 98 for people with
custom contracts?

The bulletin also states in the FAQs"

What systems are primarily at risk from the vulnerability?

While all workstations and servers are at risk regarding this
issue, systems running Microsoft Windows 2000, Windows XP, or
Windows Server 2003 are primarily at risk due to the unique
characteristics of the vulnerability and affected code path.

Does Win 98 share these "unique characteristics?"

What is the difference between "all workstations and servers"
being at risk but just some being "primarily" at risk because of
"unique characteristics."

Normally I do not log on and have the browser available, i.e., I
can't look at other systems on my local network. Does that leave
me safe?
