So client could cause buff overflow by specifying wrong
CONTENT_LENGTH in the custom-crafted headers. In that case,
even the apache's 414 Request-URI Too Large could not prevent the
problem,right?

Not to waste readers' (if any) time, I will be more detailed:

I have meant

In that case, even the apache's 414 Request-URI Too Large could not prevent the
problem, as buff overflow still could be caused for the headers smaller
than 8190 as they would pass httpd check but misinform and would
potencialy make to panic my cgi.c, right?


And there is no reliable way to determine the CONTENT_LENGTH inside the
httpd from the client input given as headers might vary, right?
