Hello Bugtraq!

As I checked this DoS vulnerability today, it also works in IE7, besides
IE6.

Vulnerable version is Internet Explorer 7 (7.0.6000.16473) and previous
versions (and potentially next versions).

P.S.

Also I wrote to Ruben Reguero two days ago, and told him that it was strange
that in Firefox 3.5 he had no problems (with this exploit). And maybe he has
last Firefox 3.5.1. After that he answered me and confirmed it.

Best wishes & regards,
