Exploiting Buffer Overflows in CGI Scripts

[franciozzy () terra com br]

Hi,

I was looking for papers on exploiting buffer overflows in CGI Scripts,
but just couldn't manage to find any.

I have several questions about:
* How apache or other webservers handles requests with binary data
  (shellcode).
* How can someone issue a "Host:" tag after the "GET ... HTTP/1.0"
  line, if the evil buffer will get apache to process the request.
* On the above topic, is there any tricks to code the shellcode in
  order to avoid the webserver to do so?

Thanks for any information on it,
Franciozzy
