General Information
Executive Summary
This security update resolves a privately reported vulnerability in
Microsoft Office Publisher that could allow remote code execution if a

Users whose accounts are configured to have fewer user rights on the
system could be less impacted than users who operate with administrative
user rights.

Vulnerability Information
Pointer Dereference Vulnerability - CVE-2009-0566
A remote code execution vulnerability exists in the way that Microsoft
Office Publisher opens, imports, and converts files created in versions
older than Microsoft Office Publisher 2007. An attacker could exploit the
vulnerability by creating a specially crafted Publisher file that could
be included as an e-mail attachment, or hosted on a specially crafted or
compromised Web site.
If a user were logged on with administrative user rights, an attacker who
successfully exploited this vulnerability could take complete control of
an affected system. An attacker could then install programs; view,
change, or delete data; or create new accounts with full user rights.
Users whose accounts are configured to have fewer user rights on the
system could be less affected than users who operate with administrative
user rights.
