Microsoft: >> Windows 10 >> 2004 Security Vulnerabilities
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.

A remote code execution vulnerability exists when Windows Media Audio Codec improperly handles objects. An attacker who successfully exploited the vulnerability could take control of an affected system.
There are multiple ways an attacker could exploit the vulnerability, such as by convincing a user to open a specially crafted document, or by convincing a user to visit a malicious webpage.
The security update addresses the vulnerability by correcting how Windows Media Audio Codec handles objects.

An information disclosure vulnerability exists in RPC if the server has Routing and Remote Access enabled. An attacker who successfully exploited this vulnerability could obtain information to further compromise the user’s system
To exploit this vulnerability, an attacker would need to run a specially crafted application against an RPC server which has Routing and Remote Access enabled. Routing and Remote Access is a non-default configuration; systems without it enabled are not vulnerable.
The security update addresses the vulnerability by correcting how the Routing and Remote Access service handles requests.

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.

An information disclosure vulnerability exists on ARM implementations that use speculative execution in control flow via a side-channel analysis, aka "straight-line speculation."
To exploit this vulnerability, an attacker with local privileges would need to run a specially crafted application.
The security update addresses the vulnerability by bypassing the speculative execution.

GRUB2 fails to validate kernel signature when booted directly without shim, allowing secure boot to be bypassed. This only affects systems where the kernel signing certificate has been imported directly into the secure boot database and the GRUB image is booted directly without the use of shim. This issue affects GRUB2 version 2.04 and prior versions.
