Security Update for Microsoft Windows SMB Server (4013389)

Published: March 14, 2017

Version: 1.0

Executive Summary

This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker sends specially crafted messages to a Microsoft Server Message Block 1.0 (SMBv1) server.

This security update is rated Critical for all supported releases of Microsoft Windows. For more information, see the Affected Software and Vulnerability Severity Ratings section.

The security update addresses the vulnerabilities by correcting how SMBv1 handles specially crafted requests.

For more information about the vulnerabilities, see the Vulnerability Information section.

For more information about this update, see Microsoft Knowledge Base Article 4013389.

Affected Software and Vulnerability Severity Ratings

The following software versions or editions are affected. Versions or editions that are not listed are either past their support life cycle or are not affected. To determine the support life cycle for your software version or edition, see Microsoft Support Lifecycle.

The severity ratings indicated for each affected software assume the potential maximum impact of the vulnerability. For information regarding the likelihood, within 30 days of this security bulletin’s release, of the exploitability of the vulnerability in relation to its severity rating and security impact, please see the Exploitability Index in the March bulletin summary.

Note Please see the Security Update Guide for a new approach to consuming the security update information. You can customize your views and create affected software spreadsheets, as well as download data via a restful API. For more information, please see the Security Updates Guide FAQ. As a reminder, the Security Updates Guide will be replacing security bulletins. Please see our blog post, Furthering our commitment to security updates, for more details.

Vulnerability Information

Multiple Windows SMB Remote Code Execution Vulnerabilities

Remote code execution vulnerabilities exist in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited the vulnerabilities could gain the ability to execute code on the target server.

To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server.

The security update addresses the vulnerabilities by correcting how SMBv1 handles these specially crafted requests.

The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:

### Mitigating Factors Microsoft has not identified any [mitigating factors](https://technet.microsoft.com/library/security/dn848375.aspx) for these vulnerabilities. ### Workarounds The following [workarounds](https://technet.microsoft.com/library/security/dn848375.aspx) may be helpful in your situation: - **Disable SMBv1** **For customers running Windows Vista and later** See [Microsoft Knowledge Base Article 2696547](https://support.microsoft.com/kb/2696547). **Alternative method for customers running Windows 8.1 or Windows Server 2012 R2 and later** For client operating systems: 1. Open **Control Panel**, click **Programs**, and then click **Turn Windows features on or off.** 2. In the Windows Features window, clear the **SMB1.0/CIFS File Sharing Support** checkbox, and then click **OK** to close the window. 3. Restart the system. For server operating systems: 1. Open **Server Manager** and then click the **Manage** menu and select **Remove Roles and Features**. 2. In the Features window, clear the **SMB1.0/CIFS File Sharing Support** check box, and then click **OK** to close the window. 3. Restart the system. **Impact of workaround.** The SMBv1 protocol will be disabled on the target system. **How to undo the workaround.** Retrace the workaround steps, and select the **SMB1.0/CIFS File Sharing Support** check box to restore the SMB1.0/CIFS File Sharing Support feature to an active state. Windows SMB Information Disclosure Vulnerability – CVE-2017-0147 ---------------------------------------------------------------- An information disclosure vulnerability exists in the way that the Microsoft Server Message Block 1.0 (SMBv1) server handles certain requests. An attacker who successfully exploited this vulnerability could craft a special packet, which could lead to information disclosure from the server. To exploit the vulnerability, in most situations, an unauthenticated attacker could send a specially crafted packet to a targeted SMBv1 server. The security update addresses the vulnerability by correcting how SMBv1 handles these specially crafted requests.

  • V1.0 (March 14, 2017): Bulletin published.

Page generated 2017-05-08 07:15-07:00.

Microsoft has released an emergency out-of-band patch for a critical flaw, affecting all supported versions of Windows.

The software giant said in an advisory Monday that the vulnerability, if exploited, could 'allow remote code execution if a user opens a specially crafted document or visits an untrusted webpage that contains embedded OpenType fonts.'

Microsoft's monthly release of patches includes security fixes for dozens of vulnerabilities.

'An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights,' the advisory added.

In other words, a previously undisclosed flaw in the way Windows handles certain fonts can allow a hacker to take over an entire machine.

Users running Windows Vista, Windows 7, 8, 8.1 and Windows RT are all affected, including those running Windows Server 2008 and later. A Microsoft spokesperson confirmed in an emailed statement that Windows 10 Insider Preview is also affected.

The 'critical'-rated software update lands almost a week after its scheduled Patch Tuesday where it typically issues security fixes. Microsoft said it believed the flaw was public but did not have any evidence to suggest it was being actively exploited.

Latest Microsoft Patches

The patch is available over Windows Update.

Security researchers from Google's Project Zero and FireEye were credited with finding the flaw.
