Descriptions

Microsoft Internet Explorer 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, leading to memory corruption, aka "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3674.

Microsoft Internet Explorer no maneja adecuadamente objetos en memoria, lo que permite a atacantes remotos ejecutar código de su elección accediendo a un objeto que (1) no fue inicializado adecuadamente o (2) es borrado, provocando una corrupción de memoria, conocido como "Uninitialized Memory Corruption Vulnerability," a different vulnerability than CVE-2009-3674.

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Microsoft Internet Explorer. User interaction is required in that a user must visit a malicious web page.
The specific flaw exists in the manipulation and parsing of certain HTML tags. The ordering of various objects in a malformed way results in memory corruption resulting in a call to a dangling pointer which can be further leveraged via a heap spray. Exploitation of this vulnerability will lead to remote system compromise under the credentials of the currently logged in user.
