-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Microsoft Windows with the Message Queuing
Service enabled. Authentication is not required to exploit this
vulnerability.

The specific flaw exists in the RPC interface defined on port 2103 with
UUID fdb3a030-065f-11d1-bb9b-00a024ea5525. During the processing of
opnum 0x06 the service copies user-supplied information into a fixed
length stack buffer. Sending at least 300 bytes will trigger a stack
based buffer overflow due to a vulnerable wcscat() call. Exploitation
of this issue can result in arbitrary code execution.

-- Vendor Response:
Microsoft has issued an update to correct this vulnerability. More
