Possible Firefox 1.5.0.2 Remote Code Execution

Posted on Buqtrq yesterday evening.

---------------------------------------------------
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.
