Notes
This is not a real security issue; it just describes the fact that the Gecko
engine of the Mozillae may be lead into a crash if you feed it with large chunks
of arbitrary binary data and label it as HTML. As the parsing garbage is displayed
during transfer any user will cancel the transfer and if you load it from the
hard disc, well than you have "DoSed" yourself, congratulations.
It's reproducable with 1.0.2, but I doubt it will ever be "fixed", as HTML parsers
generally try to make sense of anything even remotely resembling HTML.
