 Full enforcement mode goes into effect February 9, 2021

Known Exploited and Publicly Disclosed
 CVE-2020-1464 Windows Spoofing Vulnerability
 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.

Known Exploited
 CVE-2020-1380 Scripting Engine Memory Corruption Vulnerability
 A remote code execution vulnerability exists in the way that the scripting engine
handles objects in memory in Internet Explorer. The vulnerability could corrupt
memory in such a way that an attacker could execute arbitrary code in the context
of the current user. An attacker who successfully exploited the vulnerability could
gain the same user rights as the current user. If the current user is logged on with
administrative user rights, an attacker who successfully exploited the vulnerability
could take control of an affected system.
 In a web-based attack scenario, an attacker could host a specially crafted website
that is designed to exploit the vulnerability through Internet Explorer and then
convince a user to view the website. An attacker could also embed an ActiveX
control marked "safe for initialization" in an application or Microsoft Office
document that hosts the IE rendering engine. The attacker could also take
advantage of compromised websites and websites that accept or host user-
provided content or advertisements. These websites could contain specially
crafted content that could exploit the vulnerability.

Another CVE of Interest
 CVE-2020-1337 Windows Print Spooler Elevation of Privilege
Vulnerability
 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.
