Overview
The KB5046259 update, released on November 12, 2024, is a Security and Quality Rollup for the .NET Framework 4.8 specifically targeting Windows Server 2012. This update is part of Microsoft's Extended Security Updates (ESU) program, which provides critical security updates for systems that have reached their end of support. Windows Server 2012 officially reached its end of support on October 10, 2023, but organizations can still receive updates through the ESU program until October 13, 2026. This particular rollup includes cumulative security and reliability improvements, ensuring that systems remain secure and functional despite the end of mainstream support.
General Purpose
The primary purpose of KB5046259 is to enhance the security and reliability of the .NET Framework 4.8 on Windows Server 2012. This update does not introduce new security improvements but consolidates all previously released security enhancements. Among the quality and reliability improvements, it addresses several issues, including a design-time compilation error in Visual Studio for ASP.NET projects, potential infinite loops in the Common Language Runtime (CLR), and various memory management issues during garbage collection. Additionally, it resolves a security feature bypass vulnerability and improves the functionality of the UserPrincipal API for retrieving user group memberships.
General Sentiment
The general sentiment surrounding KB5046259 appears to be cautiously optimistic. Users appreciate the ongoing support through the ESU program, especially for critical systems that cannot be upgraded immediately. However, there are concerns regarding the potential installation failures on Azure Arc-enabled devices, which may deter some users from applying the update. Overall, the lack of reported issues and the focus on reliability improvements contribute to a positive outlook, although the end of support for Windows Server 2012 raises some apprehensions about future updates and support.
Known Issues
