Enjoy. :> Congrats again on finishing the port to CANVAS/MOSDEF,
although it's a shame you didn't make it to the march-release. :)

For those interested, there's a screenshot of my original exploit
in action at:

   http://kernelwars.blogspot.com/

This exploit + probably a Metasploit meterpreter-addon for it will
be released in the end of april (Immunity bought the rights to it
for 60 days, starting from 22nd february or so).

During our Blackhat-talk I'll discuss the bug in general and the
process of making a reliable exploit for it, except for the minor
but crucial part that achieves the actual write-4-primitive. That
will be kept to CANVAS-customers for a while yet. ;)

For the other two kernel bugs we'll discuss during the talk full
exploits will be released directly afterwards, including Karl's
neat remote wireless and pure in-memory kernel backdoor for
FreeBSD which he made for his 802.11 exploit. :>

Regarding the 0-day NetBSD bug that Christer will be talking about
he will mention some new techniques that might come in handy for
exploiting other kernel bugs on BSD-derived systems too, when certain
types of structs / pointers are overflowed. :> The bug itself is in
certain "ancient" BSD-code that may very well still be used in some
of the commercial Unix-systems too.

For those of you coming to BH Europe, see you there! :)
