The KB5037930 update, released on May 14, 2024, is a cumulative update for the .NET Framework 3.5 and 4.8 specifically targeting Windows Server 2022 and Azure Stack HCI version 22H2. This update is part of Microsoft's regular maintenance routine and is designed to enhance the security and reliability of the .NET Framework. While it does not introduce new security improvements, it consolidates all previously released security updates, ensuring that systems are up-to-date with the latest protections. The update also addresses various quality and reliability issues that have been reported by users, making it a crucial part of maintaining system integrity and performance.
General Purpose
The primary purpose of KB5037930 is to provide cumulative reliability improvements for the .NET Framework 3.5 and 4.8. This update addresses several specific issues: it resolves crashes that may occur when multiple threads query the ITypeInfo implementation of the same managed type, improves response times on 32-bit platforms, and ensures compliance with FIPS algorithms through MIST validated implementations. Additionally, it fixes issues related to wildcard format changes in IIS 10 and prevents application crashes when using certain methods in Windows Presentation Foundation (WPF). Overall, this update is essential for maintaining optimal performance and security in applications relying on the .NET Framework.
General Sentiment
The general sentiment surrounding KB5037930 appears to be mixed. While many users appreciate the cumulative nature of the update, which consolidates previous security improvements, there are notable concerns regarding runtime exceptions that have been reported in SQL CLR hosted scenarios. These exceptions are linked to changes in the SHA256Managed, SHA384Managed, and SHA512Managed types, leading to some frustration among developers who rely on these functionalities. However, workarounds are available, which may mitigate some of the negative feedback. Overall, while the update is seen as necessary for system maintenance, the reported issues may cause hesitation among users considering installation.
Known Issues
- Runtime exceptions in SQL CLR hosted scenarios, specifically with SHA256Managed, SHA384Managed, and SHA512Managed types.
- Error message: System.Security.HostProtectionException indicating forbidden operations by the CLR host.
- Workaround options include marking assemblies as UNSAFE or using SQL's HASHBYTES function instead of .NET's SHA-2 APIs.
- Microsoft has addressed this issue in a subsequent update (KB5043743).
