The remote web server is affected by a denial of service.
The remote host appears to be running a version of Apache 2.x that is
prior to 2.0.50. It is, therefore, affected by a denial of service
vulnerability that can be triggered by sending a specially crafted
HTTP request, which results in the consumption of an arbitrary amount
