| Heap-based buffer overflow in Windows Routing and Remote Access Service (RRAS) allows an unauthorized attacker to execute code over a network. |
| Improper access control in Windows HTTP.sys allows an authorized attacker to elevate privileges over a network. |
| External control of file name or path in Windows Telephony Service allows an authorized attacker to elevate privileges over an adjacent network. |
| Heap-based buffer overflow in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally. |
| Use after free in Microsoft Graphics Component allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Improper privilege management in Windows Remote Desktop allows an authorized attacker to elevate privileges locally. |
| Protection mechanism failure in MSHTML Framework allows an unauthorized attacker to bypass a security feature over a network. |
| Protection mechanism failure in Windows Shell allows an unauthorized attacker to bypass a security feature over a network. |
| Null pointer dereference in Windows Remote Access Connection Manager allows an unauthorized attacker to deny service locally. |
| Improper authentication in Windows Storage allows an authorized attacker to elevate privileges locally. |
| Use after free in Mailslot File System allows an authorized attacker to elevate privileges locally. |
| Heap-based buffer overflow in Windows Kernel allows an authorized attacker to elevate privileges locally. |
| Improper access control in Windows Ancillary Function Driver for WinSock allows an authorized attacker to elevate privileges locally. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Kernel allows an authorized attacker to elevate privileges locally. |
| Windows Print Spooler Elevation of Privilege Vulnerability |
| <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><strong>UPDATE</strong> August 10, 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. This security update changes the Point and Print default behavior; please see <a href="https://support.microsoft.com/help/5005652">KB5005652</a>.</p> |
| A spoofing vulnerability exists when Windows incorrectly validates file signatures. An attacker who successfully exploited this vulnerability could bypass security features and load improperly signed files.
In an attack scenario, an attacker could bypass security features intended to prevent improperly signed files from being loaded.
The update addresses the vulnerability by correcting how Windows validates file signatures. |
| 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).
When the second phase of Windows updates become available in Q1 2021, customers will be notified via a revision to this security vulnerability. If you wish to be notified when these updates are released, we recommend that you register for the security notifications mailer to be alerted of content changes to this advisory. See Microsoft Technical Security Notifications. |
