Subject: Re: Apple Safari: idn urlbar spoofing

With a specially crafted web page, an attacker can redirect
a www browser to the page, which URL (on the address bar) resembles an
arbitrary domain choosen by the attacker.

It is possible due to the fact, that apple safari supports
IDNs - http://en.wikipedia.org/wiki/Internationalized_domain_name -
and some of the UTF8 font glyphs embedded in the safari, could be used
to create an URL which contains whitespaces.

Tested with Apple Safari 3.0.2 (522.13.1) on MS Windows 2003 SE SP2
