The most severe of these vulnerabilities could allow remote code execution if a user opens a specially crafted document or visits a malicious webpage that embeds TrueType font files. An attacker would have no way to force users to visit a malicious website. Instead, an attacker would have to convince users to visit the website, typically by getting them to click a link in an email message or Instant Messenger message that takes them to the attacker's website. This security update is rated Critical for all supported releases of Microsoft Windows; for Microsoft .NET Framework 4, except when installed on Itanium-based editions of Microsoft Windows; and for Microsoft Silverlight 4 and Microsoft Silverlight 5. This security update is rated Important for Microsoft Office 2003, Microsoft Office 2007, and Microsoft Office 2010. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The vulnerability could allow remote code execution if a user opens a specially crafted TrueType font file. 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. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2011-3402. TrueType Font Parsing Vulnerability - CVE-2012-0159 A remote code execution vulnerability exists in the way that affected components handle a specially crafted TrueType font file. The vulnerability could allow remote code execution if a user opens a specially crafted TrueType font file. 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. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0159. .NET Framework Buffer Allocation Vulnerability - CVE-2012-0162 A remote code execution vulnerability exists in Microsoft .NET Framework that can allow a specially crafted Microsoft .NET Framework application to access memory in an unsafe manner. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the logged-on user. 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 view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0162. .NET Framework Index Comparison Vulnerability - CVE-2012-0164 A denial of service vulnerability exists in the way that .NET Framework compares the value of an index. An attacker who successfully exploited this vulnerability could cause applications created using WPF APIs to stop responding until manually restarted. Note that the denial of service vulnerability would not allow an attacker to execute code or to elevate their user rights in any fashion. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0164. GDI+ Record Type Vulnerability - CVE-2012-0165 A remote code execution vulnerability exists in the way that GDI+ handles validation of specially crafted EMF images. The vulnerability could allow remote code execution if a user opens a specially crafted EMF image file. 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. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0165. GDI+ Heap Overflow Vulnerability - CVE-2012-0167 A remote code execution vulnerability exists in the way that the Office GDI+ library handles validation of specially crafted EMF images embedded within an Office document. The vulnerability could allow remote code execution if a user opens a specially crafted Office document. 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. To view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0167. Silverlight Double-Free Vulnerability - CVE-2012-0176 A remote code execution vulnerability exists in Microsoft Silverlight that can allow a specially crafted Silverlight application to access memory in an unsafe manner. An attacker who successfully exploited this vulnerability could run arbitrary code in the security context of the logged-on user. 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 view this vulnerability as a standard entry in the Common Vulnerabilities and Exposures list, see CVE-2012-0176. Windows and Messages Vulnerability - CVE-2012-0180 An elevation of privilege vulnerability exists in the way that the Windows kernel-mode driver manages the functions related to Windows and Messages handling. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. An attacker could then install programs; view, change, or delete data; or create new accounts with full administrative rights.
