Microsoft Distributed Transaction Coordinator DoS - A flaw in the way MSDTC handles malformed packets could allow an attacker to hang the service and exhaust resources on the Server. If an attacker sends 20200 null characters to the MSDTC service, which listens on TCP port 3372, server resources are allocated poorly. This attack can result in MSDTC.EXE spiking at 100% cpu usage, MSDTC refusing connections and kernel resources being exhausted. This was fixed with MS02-018, although the security bulletin does not mention this vulnerability.
