## Description

WebKit in Apple Safari 3 Beta before Update 3.0.3, and iPhone before 1.0.1, does not properly handle the interaction between International Domain Name (IDN) support and Unicode fonts, which allows remote attackers to create a URL containing "look-alike characters" (homographs) and possibly perform phishing attacks.
