Title: Microsoft Windows Message Queuing Remote Buffer Overflow Vulnerability
Severity: CRITICAL
Description:
Microsoft Message Queuing (MSMQ) attempts to facilitate process communication over the Internet. It attempts to guarantee message delivery through priority queuing mechanisms.
A remote buffer overflow vulnerability affects Microsoft Windows. This issue is due to a failure of the affected functionality to properly validate the length of user-supplied strings prior to copying them into static process buffers. This vulnerability may be exploited over RPC.
The problem presents itself when an affected server receives a malicious crafted message. Apparently the MSMQ functionality fails to handle certain, unspecified messages that are excessively long. In such cases, critical memory can be overwritten, facilitating code execution.
It should be noted that the MSMQ functionality is not installed by default on Microsoft Windows operating systems. It requires a user to install it as an option. Furthermore for installation of BizTalk Server 2000 and 2002 MSMQ is required. For BizTalk Server 2004, MSMQ is an optional component.
A remote attacker may exploit this issue to execute arbitrary code with SYSTEM privileges, facilitating unauthorized access or privilege escalation.
It should be noted that MSMQ is not installed by default on affected platforms and must be manually installed for a computer to be vulnerable. The vulnerability is reportedly not present on computers that only enable MSMQ HTTP Message Delivery.
