Description

Mozilla Firefox does not properly prevent the literal rendering of homoglyph characters in IDN domain names, which allows remote attackers to spoof URLs and conduct phishing attacks, as demonstrated by homoglyphs of the / (slash) and ? (question mark) characters in a subdomain of a .cn domain name. This is a different vulnerability than CVE-2005-0233.

Note: some third parties claim that Firefox 3.0.6 is not affected, but much older versions perhaps are affected.
