Description

This module exploits a use-after-free vulnerability in Mozilla Firefox 3.6.16. An OBJECT element, mChannel, can be freed via the OnChannelRedirect method of the nsIChannelEventSink Interface. mChannel becomes a dangling pointer and can be reused when setting the OBJECTs data attribute. This module has been tested on Mac OS X 10.6.6, 10.6.7, 10.6.8, 10.7.2 and 10.7.3.

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
