Mozilla Firefox is vulnerable to Arbitrary Code Execution. This is because a flaw exists in the isLabelSafe() function in nsIDNService.cpp that is triggered when handling characters from different unicode blocks. An unauthenticated, remote attacker can exploit this, via a specially crafted IDN domain, to spoof a valid URL and conduct phishing attacks.
