This update is part of the Extended Security Updates (ESU) program, which provides critical security updates for systems that have reached their end of support. Windows Server 2012 reached its end of support on October 10, 2023, and this update is crucial for maintaining security and reliability in environments still using this operating system. The update includes cumulative security improvements and reliability enhancements aimed at addressing vulnerabilities and improving the overall performance of the .NET Framework on affected systems.

This vulnerability could potentially allow an attacker to execute arbitrary code on the affected system. In addition to security improvements, the update also resolves a rare issue that could lead to an infinite loop when a thread enters the Common Language Runtime (CLR) for the first time. Users are advised to ensure that all prerequisite updates are installed prior to applying this rollup to avoid installation issues.
