Microsoft Message Queuing vulnerable to buffer overflow

Vulnerability Note VU#763513

Original Release Date: 2005-07-01 | Last Revised: 2005-07-11


Microsoft Message Queuing contains a buffer overflow vulnerability. This could allow a remote attacker to execute arbitrary code on the system running the vulnerable software.


Microsoft Message Queuing (MSMQ) is a component of Microsoft Windows that provides messaging services. Applications send messages to, and read messages from, queues. MSMQ manages these messages to communicate across heterogeneous networks and systems that may be temporarily offline.

MSMQ contains a buffer overflow vulnerability in the processing of messages. MSMQ is not installed by default on any affected Windows operating system. MSMQ must be manually installed for an affected operating system to be vulnerable. Microsoft lists the following versions of Windows as affected:

    • Windows 2000 Service Pack 3 and Windows 2000 Service Pack 4
    • Windows XP Service Pack 1
    • Windows XP 64-Bit Edition Service Pack 1 (Itanium)
    • Windows 98 and Windows 98 SE
Exploit code is publicly available for this vulnerability and we have received reports of active exploitation.


A remote unauthenticated attacker could execute arbitrary code on the system running MSMQ.
