-- Vulnerability Details:
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.

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.
