Microsoft Internet Explorer CTreeNode Use-After-Free Remote Code Execution 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 a CTreeNode being freed and used afterward. This freed object can be later accessed by the CTreePos::GetBranch routine. An attacker can possibly leverage this situation to execute code under the context of the user running the browser.
