You`re the owner of a windows based Quake 3 engine server, like ET or RtCW?
You`re under attack, your server is used as a DrDOS amplifier?
Your provides shows you a high traffic and you just received some abuse-mails?

Then I have a good news for you:

I found a nice set of dll files to spoil getstatus exploit abuse.
The package includes a nice test-tool to check wether your server is safe or not.

I`ve tried the files on my local workstation, and they seems to do exactly what they should:
They block the attacked, but not HLSW.
I found the package on a russian gameserver hoster forum, I`m not the originator.
I`ve checked the files against VirusTotal, and they seems to be clean from any malware.

You can download the package here

addendum:
The originator of the files is Nikita which seems to be from http://www.gamenest.ru
