Technical Information

Brief overview of the risk:
This security update resolves two privately reported vulnerabilities that could allow remote code execution if a user opens a specially crafted Word file. An attacker who successfully exploited either 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.
Detailed Information on the risk:
A remote code execution vulnerability exists in the way that Microsoft Office Word handles a specially crafted Word file that includes a malformed record. 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.
