This security update resolves vulnerabilities in Microsoft Windows. The most severe of the vulnerabilities could allow remote code execution if an attacker runs a specially crafted application that connects to an iSNS Server and then issues malicious requests to the server. For more information about the vulnerabilities, see the Vulnerability Information section. For more information about this update, see Microsoft Knowledge Base Article 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. 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. 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.

For more information, please see this Microsoft TechNet article. The monthly security release includes all security fixes for vulnerabilities that affect Windows 10, in addition to non-security updates.

The updates are available via the Microsoft Update Catalog. Please note that effective December 13, , Windows 10 and Windows Server details for the Cumulative Updates will be documented in Release Notes. For a comprehensive list of updates replaced, go to the Microsoft Update Catalog , search for the update KB number, and then view update details updates replaced information is provided on the Package Details tab.

Does this update contain any additional security-related changes to functionality? In addition to the changes that are listed for the vulnerabilities described in this bulletin, this update includes defense-in-depth updates to help improve security-related features. A security feature bypass exists when Device Guard does not properly validate certain elements of a signed PowerShell script. An attacker who successfully exploited this vulnerability could modify the contents of a PowerShell script without invalidating the signature associated with the file.

Because Device Guard relies on the signature to determine the script is non-malicious, Device Guard could then allow a malicious script to execute. In an attack scenario, an attacker could modify the contents of a PowerShell script without invalidating the signature associated with the file.

The update addresses the vulnerability by correcting how Device Guard validates certain elements of signed PowerShell scripts. The following table contains links to the standard entry for each vulnerability in the Common Vulnerabilities and Exposures list:.

Microsoft has not identified any mitigating factors for this vulnerability. Microsoft has not identified any workarounds for this vulnerability. A denial of service vulnerability exists in implementations of the Microsoft Server Message Block 2. The vulnerability is due to improper handling of certain requests sent by a malicious SMB server to the client.

An attacker who successfully exploited this vulnerability could cause the affected system to stop responding until it is manually restarted. To exploit the vulnerability, an attacker could use various methods such as redirectors, injected HTML header links, etc. A remote code execution vulnerability exists when Microsoft Windows fails to properly validate input before loading certain dynamic link library DLL files. An attacker who successfully exploited the vulnerability could take 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.

To exploit the vulnerability, an attacker must first gain access to the local system and have the ability to execute a malicious application. The security update addresses the vulnerability by correcting how Windows validates input before loading DLL files.

The following workarounds may be helpful in your situation:. Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk. For detailed steps that you can use to prevent a control from running in Internet Explorer, see Microsoft Knowledge Base Article Follow these steps in this article to create a Compatibility Flags value in the registry to prevent a COM object from being instantiated in Internet Explorer.

Then, save the file by using the. You can apply this. You can also apply it across domains by using Group Policy. For more information about Group Policy, visit the following Microsoft Web sites:. How to undo the workaround Microsoft does not recommend unkilling undoing the kill action on an ActiveX control. If you do so, you may create security vulnerabilities. The kill bit is typically set for a reason that may be critical, and because of this, extreme care must be used when you unkill an ActiveX control.

Also, because the procedure is highly technical, do not continue unless you are very comfortable with the procedure. It is a good idea to read the whole procedure before you start. An information disclosure vulnerability exists when Windows dnsclient fails to properly handle requests. If the target is a workstation, the attacker could convince a user to visit an untrusted webpage.

If the target is a server, the attacker would have to trick the server into sending a DNS query to a malicious DNS server. The security update addresses the vulnerability by modifying how Windows dnsclient handles requests. An attacker who successfully exploited the vulnerability could run arbitrary code in another user's session.

To exploit the vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability once another user logged in to the same system via Terminal Services or Fast User Switching.

A remote code execution vulnerability exists in Windows when the iSNS Server service fails to properly validate input from the client, leading to an integer overflow. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SYSTEM account.

An attacker could exploit the vulnerability by creating a specially crafted application to connect to the iSNS Server and then issue malicious requests to it.
