Software:  
 Firefox Web Browser
Tested: 
 Linux, Windows clients' version 1.5.0.2
Result:  
 Firefox Remote Code Execution and Denial of Service - Vendor contacted, no patch yet.
Problem:
 A handling issue exists in how Firefox handles certain Javascript in js320.dll and xpcom_core.dll
regarding iframe.contentWindow.focus().  By manipulating this feature a buffer overflow will occur.
