   As we promised in the too short 5 minutes talk at CanSecWest last month, here we are publishing a new version of 
Impacket including all the new features we added for SMB and DCERPC. At the same time we are releasing a document 
describing what this new and weird features are, full of examples of how to use them, including a crash for MS05-039 
(UMPNP remotely exploitable buffer overflow), writen in python using this library, which can be used as base for other 
DCERPC exploits and configured in lots of different ways to send non-standard and correct trafic.

   Some of the new features are:

   * NMB and SMB (high-level implementations).
   * DCE/RPC versions 4 and 5, over different transports: UDP (version 4 exclusively), TCP, SMB/TCP, SMB/NetBIOS and 
   * Multiple ways of doing SMB tree_connect, file open, read, write.
   * SMB "fragmentation", SMB AndX command chaining.
   * Plain, NT and LM v1 authentications, using password and hashes only.
   * Portions of the following DCE/RPC interfaces: Conv, DCOM, EPM, SAMR, SvcCtl, WinReg.
   * DCERPC Alternate contexts, Multi-bind requests, Endianness selection
   * DCERPC NT and LM v1 authentication, integrity checking and encryption.
   * DCERPC v4 and v5 fragmentation, DCERPC v4 idempotent requests.
