-- 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


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.
