CVE-2011-1345

Estado: ModificadaAlta (9.3)—

Vulnerabilidad sin especificar en Microsoft Internet Explorer 8 en Windows 7 permite a atacantes remotos ejecutar código arbitrario a través de vectores de ataque desconocidos, como ha demostrado Stephen Fewer con la primera de las tres vulnerabilidades encadenadas durante el concurso Pwn2Own en la CanSecWest 2011.
