CVE-2013-3205

Microsoft Internet Explorer 6 a 8 permiten a atacantes remotos ejecutar código arbitrario o causar denegación de servicio (corrupción de memoria) a través de un sitio web manipulado, también conocido como "Vulnerabilidad de Corrupción de Memoria de Internet Explorer".

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the usage of a CCaret object. The process can be made to delete an object resulting in a dangling pointer. The process can be later forced to reuse this pointer in the CCaret::UpdateScreenCaret function resulting in a use-after-free condition. An attacker can leverage this situation to execute code under the context of the user running the browser.
