    MS12-020 Microsoft Remote Desktop Use-After-Free DoS

    This module exploits the MS12-020 RDP vulnerability originally discovered and reported by Luigi Auriemma. The flaw can be found in the way the T.125 ConnectMCSPDU packet is handled in the maxChannelIDs field, which will result an invalid pointer being used, therefore causing a denial-of-service condition.
