CVE-2011-1250
Estado: ModificadaAlta (9.3)—
Microsoft Internet Explorer 6 hasta la versión 9 no maneja apropiadamente los objetos en memoria, lo que permite a atacantes remotos ejecutar código arbitrario accediendo a un objeto que (1) no ha sido apropiadamente inicializado o (2) ha sido borrado. También conocido como "vulnerabilidad de corrupción de memoria en el manejo de propiedades Link".
CVSS
- Versión: 2.0
