| Descripción: | Summary:
This host is missing a critical security
update according to Microsoft KB4056893
Vulnerability Insight:
Multiple flaws exist due to:
- Microsoft Edge does not properly enforce cross-domain policies.
- The scripting engine handles objects in memory in Microsoft Edge.
- The scripting engine handles objects in memory in Microsoft Browsers.
- Windows Adobe Type Manager Font Driver (ATMFD.dll) fails to properly
handle objects in memory.
- Microsoft Edge PDF Reader improperly handles objects in memory.
- Windows kernel fails to properly handle objects in memory.
- An error in the way that the Windows Kernel API enforces permissions.
- An error in the Microsoft Server Message Block (SMB) Server when an attacker
with valid credentials attempts to open a specially crafted file over the SMB
protocol on the same machine.
- An error in the Windows kernel.
- Multiple errors leading to 'speculative execution side-channel attacks' that
affect many modern processors and operating systems including Intel, AMD, and ARM.
- Microsoft .NET Framework (and .NET Core) components do not completely validate
certificates.
- .NET, and .NET core, improperly process XML documents.
Vulnerability Impact:
Successful exploitation will allow an attacker
to elevate privileges, execute arbitrary code in the context of the current
user, potentially read data that was not intended to be disclosed, impersonate
processes, interject cross-process communication, or interrupt system
functionality, bypass certain security checks in the operating system and can
cause a target system to stop responding and can be used to read the content
of memory across a trusted boundary and can therefore lead to information
disclosure and some unspecified impacts too.
Affected Software/OS:
- Microsoft Windows 10 for x64 based Systems
- Microsoft Windows 10 for 32-bit Systems
Solution:
The vendor has released updates. Please see the references for more information.
