Descriptions
Microsoft Internet Explorer 6 does not properly handle objects in memory, which allows remote attackers to execute arbitrary code by accessing a deleted object, aka "OnLoad Event Remote Code Execution Vulnerability."
Microsoft Internet Explorer v6 no gestiona adecuadamente los objetos en memoria, lo que permite a atacantes remotos ejecutar código de su eleccion accediendo a un objeto eliminado. También conocida como "vulnerabilidad de ejecución remota de código del evento OnLoad".
Remote exploitation of a memory corruption vulnerability in Microsoft Corp.'s Internet Explorer could allow an attacker to execute arbitrary code with the privileges of the current user. The vulnerability occurs when a Javascript event handler such as "onload" is set to a Javascript object's attributes or childNodes collection. A event object is created and this object's memory is later freed; however, a reference to the object remains. When the reference is later used to access the event object, this now-invalid memory is treated as a valid object. The corrupt object's vtable is used to make an indirect function call. This may result in the execution of arbitrary code. Microsoft Internet Explorer 6 is vulnerable.
