Plugin commentThis vulnerability seems not to be very well documented. So perhaps Apache prior 2.0.47 are vulnerable too. Apache 1.x is not vulnerable for sure.

Bug descriptionThe remote host is running an Apache web server. Apache 2.0.47 to 2.0.49 is vulnerable to a buffer overflow in in excessively long HTTP header strings. It has been documented that only denial of service is possible. Running arbitrary code seems not to work.
