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 the DirectX version installedOpen Command Prompt and run dxdiag.exe, then check the version displayed on the System tab under DirectX VersionAffected if The version shown is 9.0, 10.0, 10.1, 11.0, or 11.1
-
Verify the Windows versionRun winver or check system properties to confirm the Windows versionAffected if The system is Windows XP SP2/SP3 through Windows Server 2012 (these are the affected OS ranges)
-
Confirm DirectPlay component is presentCheck if DirectPlay is available on the system: Go to Control Panel > Programs and Features > Turn Windows features on or off, and look for DirectPlay under Legacy Components, or check the registry key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectPlay for installed componentsAffected if DirectPlay is installed and available on the system
A system is affected if it runs DirectX version 9.0, 10.0, 10.1, 11.0, or 11.1 on a supported Windows version, and the DirectPlay component is present and enabled.

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.
dbcve · scopedApply Microsoft security update MS12-063 (or subsequent cumulative updates) to all affected systems, and consider disabling the DirectPlay component if not required for business functions.
- Enable Automatic Updates in Windows to receive Microsoft security patches automatically
