NoTelURL is a free tool developed by Jrg Voss that ensures that USSD control codes can no longer be executed without any user interaction. Samsung Galaxy S III, Galaxy Ace, Beam and the S Advance are also affected. Samsung says issue has already been fixed with an update to the Galaxy S 3. NoTel URL is responsible for handling URLs which start with TEL: the designator for links to telephone numbers. The tool reliably prevented control codes from being injected via malicious web pages and QR codes.”]
