Vulnerabilities in the Embedded OpenType Font Engine Could Allow Remote Code Execution
Description: This security update resolves two privately reported vulnerabilities in a Microsoft Windows component, the Embedded OpenType (EOT) Font Engine. The vulnerabilities could allow remote code execution. An attacker who successfully exploited either of these vulnerabilities could take complete control of an affected system remotely. 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. The update addresses the vulnerability by correcting the way that the Microsoft Windows EOT component parses files and content containing embedded fonts.
