Technical Information

Brief overview of the risk:
This security update resolves one publicly disclosed and five privately reported vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker convinces a user to open a specially crafted document or visit an untrusted website that contains embedded TrueType fonts.

Detailed Information on the risk:

An elevation of privilege vulnerability exists in the Windows kernel-mode driver (Win32k.sys) that is caused when it improperly handles objects in memory. An attacker who successfully exploited this vulnerability could gain elevated privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
