An elevation of privilege vulnerability exists when the Windows kernel fails to properly handle objects in memory. An attacker who successfully exploited this vulnerability could run arbitrary code in kernel mode. 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 first have to log on to the system. An attacker could then run a specially crafted application to take control of an affected system.

The update addresses the vulnerability by correcting how the Windows kernel handles objects in memory.

Information published. This CVE was addressed by updates that were released in July 2020, but the CVE was inadvertently omitted from the July 2020 Security Updates. This is an informational change only. Customers who have already installed the July 2020 update do not need to take any further action.

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 information disclosure vulnerability exists when the win32k component improperly provides kernel information. An attacker who successfully exploited the vulnerability could obtain information to further compromise the user’s system.

To exploit this 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 win32k handles objects in memory.

What type of information could be disclosed by this vulnerability?

The type of information that could be disclosed if an attacker successfully exploited this vulnerability is memory layout - the vulnerability allows an attacker to collect information that facilitates predicting addressing of the memory.
