This security update resolves two privately reported vulnerabilities in Microsoft
Office that could allow remote code execution if a user opens a malformed
Office file. 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 impacted than users who operate with administrative user rights.
