CVE-2013-3123

Microsoft Internet Explorer 8 hasta 10 permite a atacantes remotos ejecutar código arbitrario o causar una denegación de servicio (corrupción de memoria) a través de un sitio web especialmente diseñado, también conocido como "Vulnerabilidad de corrupción de memoria en Internet Explorer", una vulnerabilidad diferente a CVE-2013-3111.

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 CCaret object. When triggering the onscroll event, the process can be made to delete a CCaret object resulting in a dangling pointer. The process can be later forced to reuse this pointer 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.
