Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Active Directory Federation Services (AD FS). The vulnerability could allow information disclosure if a user leaves their browser open after logging off from an application, and an attacker reopens the application in the browser immediately after the user has logged off.

Severity Rating: Moderate
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if an attacker places a specially crafted TrueType font on a network share and a user subsequently navigates there in Windows Explorer. In a web-based attack scenario, an attacker could host a website that contains a webpage that is used to exploit this vulnerability. In addition, compromised websites and websites that accept or host user-provided content or advertisements could contain specially crafted content that could exploit this vulnerability. In all cases, however, an attacker would have no way to force users to visit such websites. Instead, an attacker would have to persuade users to visit a 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.

Severity Rating: Important
Revision Note: V1.0 (November 11, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow security feature bypass when Remote Desktop Protocol (RDP) fails to properly log audit events. By default, RDP is not enabled on any Windows operating system. Systems that do not have RDP enabled are not at risk.

Revision Note: V1.0 (November 6, 2014): Advance notification published.
Summary: This is an advance notification of security bulletins that Microsoft is intending to release on November 11, 2014

Revision Note: V1.0 (October 21, 2014): Advisory published.
Summary: Microsoft is aware of a vulnerability affecting all supported releases of Microsoft Windows, excluding Windows Server 2003. The vulnerability could allow remote code execution if a user opens a specially crafted Microsoft Office file that contains an OLE object. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights. The attack requires user interaction to succeed on Windows clients with a default configuration, as User Account Control (UAC) is enabled and a consent prompt is displayed.

Severity Rating: Critical
Revision Note: V1.0 (October 14, 2014): Bulletin published.
Summary: This security update resolves three privately reported vulnerabilities in Microsoft .NET Framework. The most severe of the vulnerabilities could allow remote code execution if an attacker sends a specially crafted URI request containing international characters to a .NET web application, causing ASP.NET to generate incorrectly constructed URIs. In .NET 4.0 applications, the vulnerable functionality (iriParsing) is disabled by default; for the vulnerability to be exploitable an application has to explicitly enable this functionality. In .NET 4.5 applications, iriParsing is enabled by default and cannot be disabled.

Severity Rating: Important
Revision Note: V1.0 (October 14, 2014): Bulletin published.
Summary: This security update resolves a publicly disclosed vulnerability in ASP.NET MVC. The vulnerability could allow security feature bypass if an attacker convinces a user to click a specially crafted link or to visit a webpage that contains specially crafted content designed to exploit the vulnerability. In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through a web browser, and then convince a user to view the website. The attacker could also take advantage of compromised websites and websites that accept or host user-provided content or advertisements. These websites could contain specially crafted content that could exploit these vulnerabilities. In all cases, however, an attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to click a link in an email message or in an Instant Messenger message that takes them to the attacker’s website, or by getting them to open an attachment sent through email.

Severity Rating: Critical
Revision Note: V1.0 (October 14, 2014): Bulletin published.
Summary: This security update resolves fourteen privately reported vulnerabilities in Internet Explorer. The most severe of these vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited these vulnerabilities could gain the same user rights as the current user. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than those who operate with administrative user rights.

Severity Rating: Important
Revision Note: V1.0 (October 14, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. An elevation of privilege vulnerability exists in the way the Windows FASTFAT system driver interacts with FAT32 disk partitions. An attacker who successfully exploited this vulnerability could execute arbitrary code with elevated privileges.

Severity Rating: Important
Revision Note: V1.0 (October 14, 2014): Bulletin published.
Summary: This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user opens a Microsoft Office file that contains a specially crafted OLE object. An attacker who successfully exploited this vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Customers whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.
