CVE-2007-3742

Estado: ModificadaMedia (4.3)—

WEbKit en Apple Safari 3 Beta anterior al Update 3.0.3, y iPhone anterior a 1.0.1, no maneja adecuadamente la interacción entre el soporte para Nombres de Dominio Internacionales (International Domain Name o IDN) y las fuentes Unicode, lo cual permite a atacantes remotos crear un URL conteniendo "caracteres con apariencia similar" (homógrafos), y posiblemente realizar ataques de fraude (phishing).
