CVE-2016-3369
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedMicrosoft Windows 10 Gold and 1511 allows attackers to cause a denial of service via unspecified vectors, aka "Windows Denial of Service Vulnerability."
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA denial of service vulnerability in Microsoft Windows 10 (Gold and 1511 versions) allows remote attackers to crash affected systems via unspecified vectors. The vulnerability has a CVSS base score of 7.5, indicating network-exploitable attack with low complexity and no authentication required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify Windows 10 versionRun 'winver' from the command prompt or check System Properties to view the Windows 10 build number. Alternatively, run 'systeminfo | findstr /B /C:"OS Name" /C:"OS Version"'Affected if The system runs Windows 10 Gold (initial release, build 10240) or Windows 10 version 1511 (November Update, build 10586)
-
Confirm build number preciselyRun 'winver' and note the full version string displayed (for example, 'Version 1607' or 'Build 10586'). Compare your build number against known affected builds for versions Gold and 1511Affected if The displayed build number corresponds to Windows 10 Gold or version 1511 releases
-
Verify security update installationOpen Control Panel > Programs and Features > View installed updates, or run 'powershell Get-HotFix -Id KB3189866' in an elevated command prompt. Search for security update KB3189866 (MS16-103)Affected if The system is missing security update KB3189866 or subsequent cumulative updates containing the CVE-2016-3369 fix
-
Assess network exposureDetermine if the affected Windows 10 system is directly accessible from network sources. Check firewall rules and network segmentation that permit inbound unsolicited network traffic to the systemAffected if The vulnerable Windows 10 system accepts remote network connections without adequate filtering, as the vulnerability is network-exploitable with low complexity
A system is affected if it runs Windows 10 Gold or version 1511, lacks security update KB3189866 or later cumulative updates, and is network-accessible to remote attackers.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataApply the relevant Microsoft security update (MS16-103 or subsequent cumulative updates) to all affected Windows 10 systems. For legacy systems that cannot be patched, implement network-level filtering and IDS signatures as compensating controls.
