Comment: From Microsoft's MS05-012 bulletin:
"A privilege elevation vulnerability exists in the way that the
affected operating systems and programs access memory when they process
COM structured storage files. This vulnerability could allow a
logged on user to take complete control of the system."
and
"A remote code execution vulnerability exists in OLE because of the
way that it handles input validation. An attacker could exploit the
vulnerability by constructing a malicious document that could
potentially allow remote code execution. An attacker who successfully
exploited this vulnerability could take complete control of an
affected system. However, user interaction is required to exploit this
vulnerability on Windows 2000, Windows XP, and Windows Server 2003."
