source: http://www.securityfocus.com/bid/22814/info KDE Konqueror is prone to a remote denial-of-service vulnerability because of an error in KDE's JavaScript implementation. An attacker may exploit this vulnerability to cause Konquerer to crash, resulting in denial-of-service conditions. Konqueror included with KDE version 3.5.5 is vulnerable; other versions may also be affected. Demo of how to make Konqueror 3.5.5 crash by mark@bindshell.net.

Simply load this file in Konqueror. Vulnerable versions should segfault instantly with a null pointer exception.
