Vulnerability Details
	
Message Queuing Service Remote Code Execution Vulnerability
CVE-2007-3039

A remote code execution vulnerability exists in the Message Queuing Service
when it incorrectly validates input strings before passing the strings to a
buffer. An attacker could exploit the vulnerability by constructing a
specially crafted MSMQ message that could allow remote code execution in a
remote attack scenario on Microsoft Windows 2000 Server and a local
elevation of privilege in a local scenario on Microsoft Windows 2000
Professional and Windows XP. An attacker who successfully exploited this
vulnerability could take complete control of an affected system.
