This Metasploit module exploits an 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 Metasploit module uses heapspray with a minimal ROP chain to bypass DEP on Windows XP SP3.
