Descriptions

Microsoft Internet Explorer 6 through 9 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka "Body Element Remote Code Execution Vulnerability."

Microsoft Internet Explorer v6 a v9 no trata correctamente los objetos en la memoria, lo que permite a atacantes remotos ejecutar código de su elección accediendo a un objeto eliminado. También conocida como "vulnerabilidad de ejecución remota de código a través del elemento Body".

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 way Internet Explorer handles calls to the method swapNode(). When a call to swapNode is issued on an node within a document that has two body nodes, Internet Explorer frees an attribute field for one of the body nodes and then later re-uses the freed field during the node swap. This behavior could result in remote code execution under the context of the current user.
