| Use of uninitialized resource in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to disclose information over a network. |
| Use after free in Desktop Windows Manager allows an authorized attacker to execute code locally. |
| Use of uninitialized resource in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to disclose information over a network. |
| Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Null pointer dereference in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Use of uninitialized resource in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to disclose information over a network. |
| Use after free in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Exposure of sensitive information to an unauthorized actor in Windows NT OS Kernel allows an authorized attacker to disclose information locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Integer overflow or wraparound in Windows Distributed Transaction Coordinator allows an authorized attacker to disclose information over a network. |
| Time-of-check time-of-use (toctou) race condition in Windows NTFS allows an unauthorized attacker to disclose information locally. |
| Use of uninitialized resource in Windows Routing and Remote Access Service (RRAS) allows an authorized attacker to disclose information over a network. |
| Exposure of sensitive information to an unauthorized actor in Windows File Explorer allows an unauthorized attacker to perform spoofing over a network. |
| Use after free in Desktop Windows Manager allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |

| <p>A remote code execution vulnerability exists when the Windows Print Spooler service improperly performs privileged file operations. An attacker who successfully exploited this vulnerability could run arbitrary code with SYSTEM privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.</p>
<p>UPDATE July 7, 2021: The security update for Windows Server 2012, Windows Server 2016 and Windows 10, Version 1607 have been released. Please see the Security Updates table for the applicable update for your system. We recommend that you install these updates immediately. If you are unable to install these updates, see the FAQ and Workaround sections in this CVE for information on how to help protect your system from this vulnerability.</p>
<p>In addition to installing the updates, in order to secure your system, you must confirm that the following registry settings are set to 0 (zero) or are not defined (<strong>Note</strong>: These registry keys do not exist by default, and therefore are already at the secure setting.), also that your Group Policy setting are correct (see FAQ):</p>
<ul>
<li>HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows NT\Printers\PointAndPrint</li>
<li>NoWarningNoElevationOnInstall = 0 (DWORD) or not defined (default setting)</li>
<li>UpdatePromptSettings = 0 (DWORD) or not defined (default setting)</li>
</ul>
<p><strong>Having NoWarningNoElevationOnInstall set to 1 makes your system vulnerable by design.</strong></p>
<p>UPDATE July 6, 2021: Microsoft has completed the investigation and has released security updates to address this vulnerability. Please see the Security Updates table for the applicable update for your system. We recommend that you install these updates immediately. If you are unable to install these updates, see the FAQ and Workaround sections in this CVE for information on how to help protect your system from this vulnerability.

<p>Note that the security updates released on and after July 6, 2021 contain protections for CVE-2021-1675 and the additional remote code execution exploit in the Windows Print Spooler service known as “PrintNightmare”, documented in CVE-2021-34527.</p>
