While waiting for an official patch, how about the following workaround?
RewriteEngine On
RewriteCond %{REQUEST_METHOD} ^(HEAD|GET) [NC]
RewriteCond %{HTTP:Range} ([0-9]*-[0-9]*)(\s*,\s*[0-9]*-[0-9]*)+
RewriteRule .* - [F]
The workaround uses modrewrite to forbid get|head requests with multiple ranges in the Range HTTP header.
The second regex could be improved but it works for the exploit released so far...
Cheers,
Davide.
Did not help here. Debian Squeeze with its Apache.

read on here where the apache team is resolving the issue:

Works (too) well here. Are there any workarounds other than rate
limiting or detecting + dropping the traffic IPS-wise?

Q: How many gradual (sorry, that's supposed to be "graduate") students
does it take to screw in a light bulb?
A: "I'm afraid we don't know, but make my stipend tax-free, give my
advisor a $30,000 grant of the taxpayer's money, and I'm sure he
can tell me how to do the gruntwork for him so he can take the
credit for answering this incredibly vital question."
