If you are still using Windows 7 or Windows 8.1 on your device, you might want to check for some important updates that Microsoft released on January 8, 2019. These updates are KB4480970 and KB4480964, which are part of the monthly security patch cycle that Microsoft follows for its supported operating systems.




Microsoft Releases Updates KB4480970 and KB4480964 for Windows 7 and 8.1



In this article, we will explain what these updates are, why they are important, how to get them, how to check if they are installed on your device, and how to uninstall them if you encounter any problems.


What are these updates and why are they important?




These updates are cumulative updates that contain security fixes and improvements for various components of Windows 7 and Windows 8.1. They also include some non-security enhancements that improve the performance and reliability of these operating systems.


These updates are important because they address some critical vulnerabilities that could allow remote code execution, elevation of privilege, information disclosure, or denial of service attacks on your device. These vulnerabilities affect various components such as Windows Kernel, Windows Storage and Filesystems, Windows Wireless Networking, Microsoft JET Database Engine, Microsoft Graphics Component, Microsoft Edge, Internet Explorer, ChakraCore, Windows DHCP Server, .NET Framework, ASP.NET Core MVC Frameworks Components.


By installing these updates, you can protect your device from potential exploits that could compromise your data or damage your system. KB4480970: Monthly Rollup for Windows 7 SP1 and Windows Server 2008 R2 SP1




This update is a monthly rollup that applies to devices running Windows 7 Service Pack 1 (SP1) or Windows Server 2008 R2 SP1. It includes all the security and non-security fixes that were released since the previous monthly rollup in December 2018, as well as some new improvements.


What does this update do?




This update addresses the following security issues:



  • A remote code execution vulnerability in Windows DHCP Server that could allow an attacker to run arbitrary code on a DHCP server by sending specially crafted packets. This vulnerability is rated as critical and has been assigned the CVE-2019-0547 identifier.



  • An elevation of privilege vulnerability in Windows Kernel that could allow an attacker to execute code with higher privileges by exploiting a race condition in the memory management. This vulnerability is rated as important and has been assigned the CVE-2019-0539 identifier.
