Common Vulnerabilities and Exposures assigned an identifier CVE-2009-0652 to
the following vulnerability:

Mozilla Firefox 3.0.6 does not properly prevent the literal rendering
of homoglyph characters in IDN domain names, which allows remote

subdomain of a .cn domain name, a different vulnerability than
CVE-2005-0233.
