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. The specific flaw exists during the browsers garbage collection process. When multiple DOM elements are cloned and linked to one another and the browser is reloaded, a memory corruption occurs resulting in a double free. This can be leveraged to execute arbitrary code under the context of the current user.
