CVE-2011-1346

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 desconocido, como ha demostrado Stephen Fewer con la segunda de las tres vulnerabilidades encadenadas durante el concurso Pwn2Own en la CanSecWest 2011.
