Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow a remote code execution. The vulnerability exists when the Windows font library improperly handles specially crafted embedded fonts. 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. To learn more about the vulnerability, see Microsoft Security Bulletin MS16-132.
