This security update resolves several privately reported vulnerabilities in
Microsoft Word that could allow remote code execution if a user opens a
specially crafted Word file. An attacker who successfully exploited these
vulnerabilities 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 impacted than users who
operate with administrative user rights.
