Vulnerabilities in SMB v2 Could Allow Remote Code Execution

This security update resolves one publicly disclosed and two privately reported vulnerabilities in Server Message Block Version 2 (SMBv2). The most severe of the vulnerabilities could allow remote code execution if an attacker sent a specially crafted SMB packet to a computer running the Server service. Firewall best practices and standard default firewall configurations can help protect networks from attacks that originate from outside the enterprise perimeter. Best practices recommend that systems that are connected to the Internet have a minimal number of ports exposed.

This security update is rated Critical for supported editions of Windows Vista and Windows Server 2008. For more information, see the subsection, Affected and Non-Affected Software, in this section.
Vulnerabilities in Windows Media Runtime Could Allow Remote Code Execution

This security update resolves two privately reported vulnerabilities in Windows Media Runtime. The vulnerabilities could allow remote code execution if a user opened a specially crafted media file or received specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited these vulnerabilities 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.

This security update is rated Critical for DirectShow WMA Voice Codec, Windows Media Audio Voice Decoder, and Audio Compression Manager on supported editions of Microsoft Windows 2000; Windows XP; Windows Server 2003, except for Itanium-based editions; Windows Vista; and Windows Server 2008, except for Itanium-based editions. For more information, see the subsection, Affected and Non-Affected Software, in this section.

The security update addresses the vulnerabilities by changing the manner in which the Windows Media Runtime processes ASF files and initializes functions in compressed audio files. For more information about the vulnerabilities, see the Frequently Asked Questions (FAQ) subsection for the specific vulnerability entry under the next section, Vulnerability Information.
Vulnerability in Windows Media Player Could Allow Remote Code Execution

This update resolves two newly discovered vulnerabilities. These vulnerabilities are documented in the “Vulnerability Details” section of this bulletin.

If a user is logged on with administrative user rights, 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 affected than users who operate with administrative user rights.

We recommend that customers apply the update immediately.
Cumulative Security Update for Internet Explorer
This security update resolves three privately reported vulnerabilities and one publicly disclosed vulnerability in Internet Explorer. The vulnerabilities could allow remote code execution if a user views a specially crafted Web page using 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.

Cumulative Security Update of ActiveX Kill Bits
This security update addresses a privately reported vulnerability that is common to multiple ActiveX controls and is currently being exploited. The vulnerability that affects ActiveX controls that were compiled using the vulnerable version of the Microsoft Active Template Library (ATL) could allow remote code execution if a user views a specially crafted Web page with Internet Explorer, instantiating the ActiveX control. 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.

Vulnerabilities in Microsoft Active Template Library (ATL) ActiveX Controls for Microsoft Office Could Allow Remote Code Execution
This security update resolves several privately reported vulnerabilities in ActiveX Controls for Microsoft that were compiled with a vulnerable version of Microsoft Active Template Library (ATL). The vulnerabilities could allow remote code execution if a user loaded a specially crafted component or control. 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.

Vulnerabilities in the Microsoft .NET Common Language Runtime Could Allow Remote Code Execution
This security update resolves three privately reported vulnerabilities in Microsoft .NET Framework and Microsoft Silverlight. The vulnerabilities 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) or Silverlight applications, or if an attacker succeeds in persuading a user to run a specially crafted Microsoft .NET application. 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 vulnerabilities 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 executing it, as could be the case in a Web hosting scenario. Microsoft .NET applications, Silverlight applications, XBAPs and ASP.NET pages that are not malicious are not at risk of being compromised because of this vulnerability.

Vulnerabilities in GDI+ Could Allow Remote Code Execution
This security update resolves several privately reported vulnerabilities in Microsoft Windows GDI+. These vulnerabilities could allow remote code execution if a user viewed a specially crafted image file using affected software or browsed a Web site that contains specially crafted content. 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.

Vulnerabilities in FTP Service for Internet Information Services Could Allow Remote Code Execution
This security update resolves two publicly disclosed vulnerabilities in the FTP Service in Microsoft Internet Information Services (IIS) 5.0, Microsoft Internet Information Services (IIS) 5.1, Microsoft Internet Information Services (IIS) 6.0, and Microsoft Internet Information Services (IIS) 7.0. On IIS 7.0, only FTP Service 6.0 is affected. The vulnerabilities could allow remote code execution (RCE) on systems running FTP Service on IIS 5.0, or denial of service (DoS) on systems running FTP Service on IIS 5.0, IIS 5.1, IIS 6.0 or IIS 7.0.

Vulnerabilities in Windows CryptoAPI Could Allow Spoofing
This security update resolves two publicly disclosed vulnerabilities in Microsoft Windows. The vulnerabilities could allow spoofing if an attacker gains access to the certificate used by the end user for authentication.

Vulnerability in Indexing Service Could Allow Remote Code Execution
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow remote code execution if an attacker set up a malicious Web page that invokes the Indexing Service through a call to its ActiveX component. This call could include a malicious URL and exploit the vulnerability, granting the attacker access to the client system with the privileges of the user browsing the Web page. 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.

Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege
This security update resolves several privately reported vulnerabilities in the Windows kernel. The most severe of the vulnerabilities could allow elevation of privilege if an attacker logged on to the system and ran a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit any of these vulnerabilities. The vulnerabilities could not be exploited remotely or by anonymous users.

Vulnerability in Local Security Authority Subsystem Service Could Allow Denial of Service
This security update resolves a privately reported vulnerability in Microsoft Windows. The vulnerability could allow denial of service if an attacker sent a maliciously crafted packet during the NTLM authentication process.
