CVE-2011-2001
Estado: ModificadaAlta (9.3)—
Microsoft Internet Explorer v6 a v9 no trata correctamente los objetos en la memoria, lo que permite a atacantes remotos ejecutar código de su elección a través de un intento de acceso a una tabla de una función virtual después de que la corrupción de esta tabla se haya producido. También conocida como "vulnerabilidad de ejecución remota de código por corrupción de la Tabla de Función Virtual".
CVSS
- Versión: 2.0
- Vector: AV:N/AC:M/Au:N/C:C/I:C/A:C
