Two vulnerabilities have been reported in Microsoft Windows, which can be exploited by malicious people to compromise a user's system.
1) An integer truncation error in the Embedded OpenType (EOT) Font Engine component when parsing data records in embedded fonts can be exploited to cause a heap-based buffer overflow via a specially crafted embedded font.
2) An integer overflow error in the Embedded OpenType (EOT) Font Engine component when parsing name tables in embedded fonts can be exploited to corrupt memory via a specially crafted embedded font.
Successful exploitation of the vulnerabilities allows execution of arbitrary code when a user e.g. visits a malicious web page.
