| Descripción: | Summary:
This host is missing a critical security
update according to Microsoft KB4467697.
Vulnerability Insight:
Multiple flaws exist:
- when DirectX improperly handles objects in memory.
- in Windows when the Win32k component fails to properly handle objects in
memory.
- when an open source customization for Microsoft Active Directory Federation
Services (AD FS) does not properly sanitize a specially crafted web request to
an affected AD FS server.
- when Windows Search handles objects in memory.
- in the way that the Microsoft RemoteFX Virtual GPU miniport driver handles
objects in memory.
- An elevation of privilege exists in Windows COM Aggregate Marshaler.
- when the win32k component improperly provides kernel information.
- in the way that the VBScript engine handles objects in memory.
- A security feature bypass exists when Windows incorrectly validates kernel
driver signatures.
- in PowerShell that could allow an attacker to execute unlogged code.
- in the way that Windows Deployment Services TFTP Server handles objects in
memory.
- in the way that Microsoft Graphics Components handle objects in memory.
- when Kernel Remote Procedure Call Provider driver improperly initializes
objects in memory.
- when the Windows kernel improperly initializes objects in memory.
- when VBScript improperly discloses the contents of its memory, which could
provide an attacker with information to further compromise the user's computer
or data.
- when PowerShell improperly handles specially crafted files.
Vulnerability Impact:
Successful exploitation will allow an attacker
to run arbitrary code, bypass security restrictions and load improperly signed
drivers into the kernel, gain the same user rights as the current user, obtain
information to further compromise the user's system, improperly discloses file
information and escalate privileges.
Affected Software/OS:
- Microsoft Windows 8.1 for 32-bit/x64
- Microsoft Windows Server 2012 R2
Solution:
The vendor has released updates. Please see the references for more information.
