Descriptions
Microsoft Internet Explorer 6 through 8 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 "DOM Modification Memory Corruption Vulnerability."
Microsoft Internet Explorer v6 hasta v8 no maneja adecuadamente objetos en memoria, lo que permite a atacantes remotos ejecutar código accediendo a un objeto que (1) no fue correctamente inicializado o (2) es borrado, también conocido como "DOM Modification 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 specific flaw exists within how the application handles multiple javascript modifications to the document. In certain instances the application will free an object due to a modification and then later access it again when attempting to destroy it. This re-use can lead to code execution under the context of the application.
