| An elevation of privilege vulnerability exists when an attacker establishes a vulnerable Netlogon secure channel connection to a domain controller, using the Netlogon Remote Protocol (MS-NRPC). An attacker who successfully exploited the vulnerability could run a specially crafted application on a device on the network.
To exploit the vulnerability, an unauthenticated attacker would be required to use MS-NRPC to connect to a domain controller to obtain domain administrator access.
Microsoft is addressing the vulnerability in a phased two-part rollout. These updates address the vulnerability by modifying how Netlogon handles the usage of Netlogon secure channels.
For guidelines on how to manage the changes required for this vulnerability and more information on the phased rollout, see How to manage the changes in Netlogon secure channel connections associated with CVE-2020-1472 (updated September 28, 2020).

An attacker who successfully exploited the vulnerability could retrieve the memory address of a kernel object.
To exploit the vulnerability, an attacker would have to log on to an affected system and run a specially crafted application.
The security update addresses the vulnerability by correcting how the Windows kernel handles memory addresses. |
| An elevation of privilege vulnerability exists when the Windows Print Spooler service improperly allows arbitrary writing to the file system. An attacker who successfully exploited this vulnerability could run arbitrary code with elevated system privileges. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.
To exploit this vulnerability, an attacker would have to log on to an affected system and run a specially crafted script or application.
The update addresses the vulnerability by correcting how the Windows Print Spooler Component writes to the file system. |
| <p>A remote code execution vulnerability exists in the way that the Windows Graphics Device Interface (GDI) handles objects in the memory. An attacker who successfully exploited this vulnerability could take control of the 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.</p>
<p>There are multiple ways an attacker could exploit the vulnerability:</p>
<ul>
<li>In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability and then convince users to view the website. An attacker would have no way to force users to view the attacker-controlled content. Instead, an attacker would have to convince users to take action, typically by getting them to open an email attachment or click a link in an email or instant message.</li>
<li>In a file-sharing attack scenario, an attacker could provide a specially crafted document file that is designed to exploit the vulnerability, and then convince users to open the document file.</li>
</ul>
<p>The security update addresses the vulnerability by correcting the way that the Windows GDI handles objects in the memory.</p> |
| <p>A remote code execution vulnerability exists in the way that Microsoft Windows Codecs Library handles objects in memory. An attacker who successfully exploited this vulnerability could take control of the affected system.
