Mozilla Firefox tree Object Removal Remote Code Execution Vulnerability

This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. 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 the support for XUL objects. If a specific property of a tree object is set and the parent node attempts to remove the child, the process can be made to access invalid memory. This can be abused by an attacker to execute remote code under the context of the user running the browser.
