i've made a port of mangleme: http://felinemenace.org/~nd/htmler.py with a few extra quirks (such as file extentions/url types) it finds IE bugs after roughly 2.5 -> 3 hours and they are at: http://felinemenace.org/~nd/crash_ie/ They are not the null pointer dereference that Michal found (which curiously seems to not own my 6.0.2800.1106.xpsp1?) but some other probably non-exploitable problems! htmler.py doesn't use CGI like mangleme but generates webpages in the directory 'html1' numbered 0.html to n.html. 0.html then uses a refresh to load 1.html and so on with little user interaction required! anyway, if you find bugs with it, don't sell to anyone/notify vendors! - nd -- http://felinemenace.org/~nd - "eat a duck"
