How to Fix CVE-2017-0001: Security vulnerability in Windows GDI

WARNING: This vulnerability is on the CISA Known Exploited Vulnerabilities catalog (added 2022-03-03). Federal civilian agencies must remediate by 2022-03-24. Treat it as active exploitation, not theoretical.

What is CVE-2017-0001?

The Graphics Device Interface (GDI) in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607 allows local users to gain privileges via a crafted application, aka "Windows GDI Elevation of Privilege Vulnerability." This vulnerability is different from those described in CVE-2017-0005, CVE-2017-0025, and CVE-2017-0047.

Am I affected?

Run the version check that matches your platform:

# Windows
winget list | findstr /I "windows"
Get-WmiObject Win32_Product | Where-Object { $_.Name -like "*Windows GDI*" } | Select-Object Name, Version

Compare what you see against the Affected row above (Microsoft Corporation Windows GDI The Graphics Device Interface (GDI) in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607). If your build sits inside that range, you are exposed and should patch.

How to fix CVE-2017-0001

The primary fix is to upgrade Windows GDI to the patched build. Use the commands for your platform below; the patched version listed in the vendor advisory is: See vendor advisory.

Windows (PowerShell, run as administrator)

# Check installed version
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

# Apply latest Microsoft security updates (Windows Update)
Install-Module -Name PSWindowsUpdate -Force -SkipPublisherCheck
Import-Module PSWindowsUpdate
Get-WindowsUpdate -MicrosoftUpdate
Install-WindowsUpdate -MicrosoftUpdate -AcceptAll -AutoReboot

# Or via winget for application-level patches
winget upgrade --all --accept-source-agreements --accept-package-agreements

If the affected component is a third-party application, identify the package and run:

winget upgrade --id <vendor.product>

Replace <vendor.product> with the actual winget identifier (run winget search Windows GDI to find it).

If you can't patch immediately

If you cannot apply the patched version today, restrict exposure with one of the following runnable controls. None replace the patch.

Windows firewall isolation

# Allow only management subnet to reach the vulnerable service
New-NetFirewallRule -DisplayName "Restrict Windows GDI" `
    -Direction Inbound -Action Block -RemoteAddress Any `
    -Protocol TCP -LocalPort 443
New-NetFirewallRule -DisplayName "Allow Mgmt Windows GDI" `
    -Direction Inbound -Action Allow -RemoteAddress 10.0.0.0/8 `
    -Protocol TCP -LocalPort 443

Service-level fallback

# If the affected feature is optional, stop the service until the patch is applied
sudo systemctl stop windows
sudo systemctl disable windows

How to verify the fix worked

# Linux
windows --version 2>/dev/null || dpkg -s windows | grep -i version
rpm -q windows 2>/dev/null || true

# Windows
winget list | findstr /I "windows"
Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 5

Expected: the reported version is at or above the patched build documented in the advisory. Restart any services that loaded the old library (systemctl restart <service> on Linux, restart the Windows service or reboot when prompted). For network appliances, run show version on the device and confirm the build matches the patched release.

Is CVE-2017-0001 actually being exploited?

According to the data sources above, yes, CISA has it listed as actively exploited. Either way, the fix is the same: apply the vendor patch.

Do I need to reboot after patching?

For OS or kernel updates, yes. For most userland packages a systemctl restart <service> is enough. Any process that loaded the old shared library keeps using it until restarted, so when in doubt, reboot.

What is the CVSS score?

7.8 (high). Refer to the vendor advisory for the exact vector string.
