KB4340556 .NET Framework Security & Quality Rollup updates - Windows 7

Quote:
Security and Quality Rollup updates for .NET Framework 3.5.1, 4.5.2, 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1 and 4.7.2 for Windows 7 SP1 and Server 2008 R2 SP1 (KB 4340556)

Applies to: Microsoft .NET Framework 4.7.1, Microsoft .NET Framework 4.7, Microsoft .NET Framework 4.6.2, Microsoft .NET Framework 4.6.1, .NET Framework 4.6, .NET Framework 4.5.2, Microsoft .NET Framework



This update also applies to the following:
  • Microsoft .NET Framework 4.7.2
Summary

This security update resolves the following vulnerabilities:
  • A "remote code execution" vulnerability exists when .NET Framework does not validate input correctly. An attacker who successfully exploits this vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts that have full user rights. Users whose accounts are configured to have fewer user rights on the system could be less affected than users who have administrative user rights. To exploit the vulnerability, an attacker would have to pass specific input to an application through susceptible .NET Framework methods. This security update addresses the vulnerability by correcting how .NET Framework validates input. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-8284.
  • An "elevation of privilege" vulnerability exists in .NET Framework that could allow an attacker to elevate their user rights level. To exploit the vulnerability, an attacker would first have to access the local computer, and then run a malicious program. This update addresses the vulnerability by correcting how .NET Framework enables COM objects. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-8202.
  • A "security feature bypass" vulnerability exists when .NET Framework components do not correctly validate certificates. An attacker could present expired certificates when challenged. This security update addresses the vulnerability by making sure that .NET Framework components correctly validate certificates. To learn more about this vulnerability, see Microsoft Common Vulnerabilities and Exposures CVE-2018-8356.
Important
  • All updates for .NET Framework 4.6, 4.6.1, 4.6.2, 4.7, 4.7.1 and 4.7.2 require the d3dcompiler_47.dll to be installed. We recommend that you install the included d3dcompiler_47.dll before you apply this update. For more information about the d3dcompiler_47.dll, see KB 4019990.
  • If you install a language pack after you install this update, you must reinstall this update. Therefore, we recommend that you install any language packs that you need before you install this update. For more information, see Add language packs to Windows.

This is still sitting in my updates 'unchecked' along with KB4054530, also unchecked. Do you think they're safe to install, or is it possible that MS could pull them?
