CVE-2010-2559

Estado: ModificadaAlta (9.3)—

Microsoft Internet Explorer 8 no maneja apropiadamente los objetos en memoria, lo que permite a atacantes remotos ejecutar código de su elección accediendo a un objeto que (1) no haya sido inicializado apropiadamente o (2) está borrado, lo que implica corrupción de memoria. También conocido cómo "Uninitialized Memory Corruption Vulnerability" (Vulnerabilidad de corrupción de memoria sin inicializar), una vulnerabilidad diferente a CVE-2009-3671, CVE-2009-3674, CVE-2010-0245, and CVE-2010-0246.
