Internet Explorer 6-8 has a use-after-free bug where a malicious website can trick the browser into accessing memory that was already freed, allowing attackers to run arbitrary code on your computer.

Technical detail

A use-after-free vulnerability in Internet Explorer 6-8 allows remote attackers to execute arbitrary code by crafting a web page that references a freed object (such as CDwnBindInfo), exploiting memory management flaws. The attack requires only that a user visits a malicious website; no additional user interaction or authentication is needed, resulting in complete system compromise.
