Microsoft Security Bulletin: December 2013 Release

It’s that time again! Get your updates done before the silly season starts. It’s a busy month this month with 11 updates for you to consider in your environments. Today’s update also includes firmware updates for Surface RT, Surface Pro, Surface 2 and Surface Pro 2. If you have one of those then you get an update today as well.

Bulletin ID	Bulletin Title and Executive Summary	Maximum Severity Rating and Vulnerability Impact	Restart Requirement	Affected Software
MS13-096	Vulnerability in Microsoft Graphics Component Could allow Remote Code Execution (2908005 ) This security update resolves a publicly disclosed vulnerability in Microsoft Windows, Microsoft Office, and Microsoft Lync. The vulnerability could allow remote code execution if a user views content that contains specially crafted TIFF files.	Critical  Remote Code Execution	May require restart	Microsoft Windows, Microsoft Office, Microsoft Lync
MS13-097	Cumulative Security Update for Internet Explorer (2898785 ) This security update resolves seven privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted webpage using Internet Explorer. An attacker who successfully exploited the most severe of these vulnerabilities could gain the same user rights as the current 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.	Critical  Remote Code Execution	Requires restart	Microsoft Windows, Internet Explorer
MS13-098	Vulnerability in Windows Could Allow Remote Code Execution (2893294 ) This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if a user or application runs or installs a specially crafted, signed portable executable (PE) file on an affected system.	Critical  Remote Code Execution	Requires restart	Microsoft Windows
MS13-099	Vulnerability in Microsoft Scripting Runtime Object Library Could Allow Remote Code Execution (2909158) This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker convinces a user to visit a specially crafted website or a website that hosts specially crafted content. 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.	Critical  Remote Code Execution	May require restart	Microsoft Windows
MS13-105	Vulnerabilities in Microsoft Exchange Server Could Allow Remote Code Execution ( 2915705 ) This security update resolves three publicly disclosed vulnerabilities and one privately reported vulnerability in Microsoft Exchange Server. The most severe of these vulnerabilities exist in the WebReady Document Viewing and Data Loss Prevention features of Microsoft Exchange Server. These vulnerabilities could allow remote code execution in the security context of the LocalService account if an attacker sends an email message containing a specially crafted file to a user on an affected Exchange server. The LocalService account has minimum privileges on the local system and presents anonymous credentials on the network.	Critical  Remote Code Execution	Does not require restart	Microsoft Exchange
MS13-100	Vulnerabilities in Microsoft SharePoint Server Could Allow Remote Code Execution (2904244) This security update resolves multiple privately reported vulnerabilities in Microsoft Office server software. These vulnerabilities could allow remote code execution if an authenticated attacker sends specially crafted page content to a SharePoint server. An attacker who successfully exploited these vulnerabilities could run arbitrary code in the security context of the W3WP service account on the target SharePoint site.	Important  Remote Code Execution	May require restart	Microsoft SharePoint
MS13-101	Vulnerabilities in Windows Kernel-Mode Drivers Could Allow Elevation of Privilege (2880430 ) This security update resolves five privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to a system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.	Important  Elevation of Privilege	Requires restart	Microsoft Windows
MS13-102	Vulnerability in LRPC Client Could Allow Elevation of Privilege ( 2898715 ) This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker spoofs an LRPC server and sends a specially crafted LPC port message to any LRPC client. An attacker who successfully exploited the vulnerability could then install programs; view, change, or delete data; or create new accounts with full administrator rights. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability.	Important  Elevation of Privilege	Requires restart	Microsoft Windows
MS13-103	Vulnerability in ASP.NET SignalR Could Allow Elevation of Privilege (2905244 ) This security update resolves a privately reported vulnerability in ASP.NET SignalR. The vulnerability could allow elevation of privilege if an attacker reflects specially crafted JavaScript back to the browser of a targeted user.	Important  Elevation of Privilege	Does not require restart	Microsoft Developer Tools
MS13-104	Vulnerability in Microsoft Office Could Allow Information Disclosure (2909976) This security update resolves one privately reported vulnerabilityin Microsoft Office that could allow information disclosure if a user attempts to open an Office file hosted on a malicious website. An attacker who successfully exploited this vulnerability could ascertain access tokens used to authenticate the current user on a targeted SharePoint or other Microsoft Office server site.	Important  Information Disclosure	May require restart	Microsoft Office
MS13-106	Vulnerability in a Microsoft Office Shared Component Could Allow Security Feature Bypass (2905238) This security update resolves one publicly disclosed vulnerabilityin a Microsoft Office shared component that is currently being exploited. The vulnerability could allow security feature bypass if a user views a specially crafted webpage in a web browser capable of instantiating COM components, such as Internet Explorer. In a web-browsing attack scenario, an attacker who successfully exploited this vulnerability could bypass the Address Space Layout Randomization (ASLR) security feature, which helps protect users from a broad class of vulnerabilities. The security feature bypass by itself does not allow arbitrary code execution. However, an attacker could use this ASLR bypass vulnerability in conjunction with another vulnerability, such as a remote code execution vulnerability that could take advantage of the ASLR bypass to run arbitrary code.	Important  Security Feature Bypass	May require restart	Microsoft Office

Happy updating!
