Web Analytics

There's a new important bug in apache webserver, all versions are affectedtand allows remote attackers to cause a denial of service DoS (memory and CPU consumption) via a Range header that expresses multiple overlapping ranges.

I've just tested it, and looks like latest Urchin Software releases aren't affected 6.603 and 7.100 .
