Descriptions

Microsoft Internet Explorer 5.01, 6, and 7 allows remote attackers to execute arbitrary code by causing Internet Explorer to access an uninitialized or deleted object, related to prototype variables and table cells, aka "Uninitialized Memory Corruption Vulnerability."

Microsoft Internet Explorer versiones 5.01, 6 y 7 permite a los atacantes remotos ejecutar código arbitrario causando que Internet Explorer acceda a un objeto no inicializado o eliminado, relacionado con variables prototipo y celdas de tabla, también se conoce como "Uninitialized Memory Corruption Vulnerability".

This vulnerability allows 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.
The flaw is specifically exposed when a prototype variable points to a table cell and then that table cell is removed. This results in an invalid pointer dereference which can be leveraged to result in arbitrary code execution.
