Severity Rating: Critical
Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Windows Media Player and Windows Media Center. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Digital Video Recording (.dvr-ms) file. In all cases, a user cannot be forced to open the file; for an attack to be successful, a user must be convinced to do so.

Severity Rating: Important
Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application designed to send a device event message to a higher-integrity process. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.

Severity Rating: Critical
Revision Note: V1.1 (December 13, 2011): Corrected the kill bit information for the HP Photo Creative ActiveX control in the section, Third-Party Kill Bits. This is an informational change only. There were no changes to the security update files or detection logic.
Summary: This security update resolves a privately reported vulnerability in Microsoft software. The vulnerability could allow remote code execution if a user views a specially crafted Web page that instantiates a specific ActiveX control with Internet Explorer. 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. This update also includes kill bits for four third-party ActiveX controls.

Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Active Directory, Active Directory Application Mode (ADAM), and Active Directory Lightweight Directory Service (AD LDS). The vulnerability could allow remote code execution if an attacker logs on to an Active Directory domain and runs a specially crafted application. To exploit this vulnerability, an attacker would first need to acquire credentials to log on to an Active Directory domain.

Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves four privately reported vulnerabilities in Microsoft Office. The most severe vulnerabilities could allow remote code execution if a user opens a specially crafted Publisher file. An attacker who successfully exploited any of these vulnerabilities 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.

Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in all supported editions of Windows XP and Windows Server 2003. This security update is rated Important for all supported editions of Windows XP and Windows Server 2003. Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008 R2 are not affected by the vulnerability. 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 file that contains a specially crafted OLE object. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.

Severity Rating: Critical
Revision Note: V1.0 (December 13, 2011): Bulletin published.
Summary: This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a specially crafted document or visits a malicious Web page that embeds TrueType font files.

Severity Rating: Critical
Revision Note: V2.4 (November 30, 2011): Corrected the bulletin replacement information for .NET Framework 4 on Windows 7 for x64-based Systems Service Pack 1, Windows Server 2008 R2 for x64-based Systems Service Pack 1, and Windows Server 2008 R2 for Itanium-based Systems Service Pack 1. This is a bulletin change only. There were no changes to the detection or security update files.
Summary: This security update resolves a publicly disclosed vulnerability in Microsoft .NET Framework. The vulnerability could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs). 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 vulnerability could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and then executes the page, as could be the case in a Web hosting scenario. This vulnerability could also be used by Windows .NET applications to bypass Code Access Security (CAS) restrictions.

Severity Rating: Important
Revision Note: V2.1 (November 15, 2011): Corrected the install verification registry keys, update log file name, and removal information for Windows XP and Windows Server 2003. This is an informational change only.
Summary: This security update resolves a publicly disclosed vulnerability in the MHTML protocol handler in Microsoft Windows. The vulnerability could allow information disclosure if a user opens a specially crafted URL from an attacker's web site. An attacker would have to convince the user to visit the web site, typically by getting them to follow a link in an e-mail message or Instant Messenger message.

Severity Rating: Important
Revision Note: V2.0 (November 8, 2011): Rereleased this bulletin to announce availability of an update for Windows 7 Embedded. No other update packages are affected by this rerelease.
Summary: This security update resolves a publicly disclosed vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a legitimate rich text format file (.rtf), text file (.txt), or Word document (.doc) that is located in the same network directory as a specially crafted dynamic link library (DLL) file. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. 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.
