True, as the rule is written it's only a recon. Still it's CAN
description tells me:

<quote>
Buffer overflow in Internet Printing ISAPI extension in Windows 2000
allows remote attackers to gain root privileges via a long print request
that is passed to the extension through IIS 5.0.
</quote>

Then pointing to that reference is wrong.

Shouldn't there be a rule matching that specific buffer overrun?
