Description:   Several vulnerabilities were reported in Microsoft Windows. A remote user can execute arbitrary code on the target system. A local user can gain elevated privileges on the target system.

A remote user can supply a specially crafted network message to the Microsoft Distributed Transaction Coordinator to trigger a buffer overflow and execute arbitrary code on the target system. On some configurations, authentication is required to exploit this vulnerability.

The process that COM+ uses to create and use memory structures contains a vulnerability. A remote user can execute arbitrary code on the target system.

A local user can also exploit these flaws to gain elevated privileges.

The process that the Distributed Transaction Coordinator uses to validate TIP requests contains a vulnerability. A remote user can supply a specially crafted network message to cause the Microsoft Distributed Transaction Coordinator to stop working. This can also be exploited to affect the Distributed Transaction Coordinator on other systems.
