Safari for windows 5.1.7 (7534.57.2) Remote code execution

############################################
Safari for windows 5.1.7 (7534.57.2) Remote code execution
JavaScriptCore.dll (7534.57.3.3)
Vendor notify: NO Exploit available: Private
Advisore:http://lostmon.blogspot.com.es/2013/12/safari-for-windows-517-7534572-remote.html
 #############################################

Safari for windows is a discontinued product; but in my work ) tecnical support for clients and bussines) i found it installed in serveral machines.

Iit is prone vulnerable to a buffer overflow in  JavaScriptCore.dll that allows remote crash if failed or Remote Code Execution if the exploit is succesfully.

This issue is tiggered when safari try to allocate a large amount of data in  javascript stack memory.
We espect a " out of memory" alert box, but we can bypass or fuzzing this alert and result a RCE.

 i don't like the responses from Apple amd this is a discontinued product.... See Windbg Log for this issue:

Arora qrc: dialog XSS and DoS

########################################
Arora qrc: dialog XSS and DoS
Vendor URL:http://code.google.com/p/arora/
Advisore: http://lostmon.blogspot.com.es/2012/07/arora-qrc-dialog-xss-and-dos.html
Vendor notify:NO  exploit available:yes
#######################################

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>
