Microsoft revised the security bulletin MS10-025 because the original security update did not protect systems from the vulnerability described in the bulletin. This security bulletin, rated “Critical”, was supposed to address “Remote Code Execution” vulnerability in Microsoft Windows 2000 Server running Windows Media Services,
I will suggest users to apply one of the workarounds described in the bulletin. This will help mitigate the impact of affected systems until a revised security update is made available. To view updated information of this bulletin and the workaround please visit the Microsoft Security Bulletin MS10-025 – Critical page.
