Descriptions

Use-after-free vulnerability in the CElement object implementation in Microsoft Internet Explorer 11 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via crafted JavaScript that improperly interacts with use of the Cascading Style Sheets (CSS) empty-cells property for a TABLE element, aka "Internet Explorer Memory Corruption Vulnerability."

Vulnerabilidad de uso después de liberación de memoria en la implementación del objeto CElement en Microsoft Internet Explorer 11 permite a atacantes remotos ejecutar código arbitrario o provocar una denegación de servicio (corrupción de memoria) a través de JavaScript manipulado que interactúa indebidamente con el uso de la propiedad empty-cells de Cascading Style Sheets (CSS) en un elemento TABLE, también conocida como 'Internet Explorer Memory Corruption Vulnerability'.

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 vulnerability relates to how Internet Explorer performs layout of table cells when the CSS empty-cells property is specified. By manipulating a document's elements an attacker can force a CElement-derived object in memory to be reused after it has been freed. An attacker can leverage this vulnerability to execute code under the context of the current process.
