Description

The combined, single character, version of the letter &#39;i&#39; with any of the potential accents in unicode, such as acute or grave, can be spoofed in the addressbar by the dotless version of &#39;i&#39; followed by the same accent as a second character with most font sets. This allows for domain spoofing attacks because these combined domain names do not display as punycode. This vulnerability affects Firefox
