The Microsoft Security Response Center (MSRC)
MS10-025 is a security update that only affects Windows 2000 Server customers who have installed Windows Media Services (this is a non-default configuration). Today we pulled the update because we found it does not address the underlying issue effectively. We are not aware of any active attacks seeking to exploit this issue and are targeting a re-release of the update for next week.
Customers should review the bulletin for mitigations and workarounds and those with internet facing systems with Windows Media Services installed should evaluate and use firewall best practices to limit their overall exposure.
