HTML exploit code

Greetings,

during the work on my bachelor thesis I did some penetration testing with webkit. I found serval bugs. I'll report them here now stept by step. The exploid code is attached.

========================
= System specification =

WebKit version: r90943 nighty build
Operating system: Ubuntu 10.04 LTS x86 with all updates 
CPU: Intel Core 2 Duo
Memory: 2 GB

===================
= System behavior =

WebKit Test Browser (QtTestBrowser) is startet as a normal user. User opens a prepareted website on a remote webserver. The browser opens the website and after just a second it is no longer possible to use the system. After around 30 seconds the grapical user interface will be closed and you can see that several demons are killed. The only way to get back an working system is to restart it.
