update according to Microsoft KB4048953
Vulnerability Insight:
Multiple flaws exist due to:
- An error when the Windows kernel fails to properly initialize a memory address.
- A security feature bypass when Device Guard incorrectly validates an untrusted
file.
- An error in the way that Microsoft Edge handles cross-origin requests.
- An error when the scripting engine does not properly handle objects in memory
in Internet Explorer.
- An error in the way the scripting engine handles objects in memory in Microsoft
browsers.
- An error in the way that the scripting engine handles objects in memory in
Microsoft Edge.
- An error when the Windows GDI component improperly discloses kernel memory
addresses.
- An error when Windows Search improperly handles objects in memory.
- An error when Internet Explorer improperly accesses objects in memory.
- An error in the way that Microsoft browsers access objects in memory.
- An error when the scripting engine does not properly handle objects in

- An error when the Windows kernel fails to properly handle objects in memory.
Vulnerability Impact:
Successful exploitation will allow an attacker
to gain access to potentially sensitive information, fake unsigned file appear
to be signed, determine the origin of all web pages in the affected browser,
gain the same user rights as the current user, cause a remote denial of service
against a system, test for the presence of files on disk, force the browser to
send data that would otherwise be restricted to a destination website of the
attacker's choice and run arbitrary code in kernel mode.
Affected Software/OS:
- Microsoft Windows Server 2016
- Microsoft Windows 10 Version 1607 x32/x64
