Who is Vulnerable?
Vulnerability Description	The Microsoft Distributed Transaction Coordinator (MSDTC) is a transaction infrastructure for distributed systems. It is implemented on the Windows platform as a service. The MSDTC facilitates the interactions between independent programs in a distributed system. A denial of service vulnerability exists in the DTC (Distributed Transaction Coordinator) component of Microsoft Windows. The flaw is caused by insufficient verification of user supplied data. The successful exploitation of the vulnerability may allow an attacker to cause the affected system to stop accepting requests. In the case of a successful attack, the affected service will terminate. All existing transactions and connections will be aborted and services that depend on the vulnerable service may be affected as well. The affected service is not restarted automatically, and must be started manually to resume functionality.
