Descriptions
Microsoft Internet Explorer 8 and 9 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing an object that (1) was not properly initialized or (2) is deleted, aka "Layout Memory Corruption Vulnerability."
Microsoft Internet Explorer 8 y 9 no maneja adecuadamente los objetos en memoria, lo qeu permite a atacantes remotos ejecutar código de su elección accediendo a un objeto que (1) no haya sido iniciado adecuadamente o (2) sea eleiminado. También se conoce como "Vulnerabilidad de Diseño de Corrupción de Memoria"
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of 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 way Internet Explorer handles unusual values for the layout-grid-char style property. Specific values may result in the destruction of a tree node that is still in use during the rendering of the HTML page. The resulting use-after-free vulnerability can be leveraged to achieve remote code execution.
