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. (Discovered by regenrecht). This module uses heapspray
with a minimal ROP chain to bypass DEP on Windows XP SP3. Additionlay,
a windows 7 target was provided using JAVA 6 and below to avoid aslr.
