CVE-2024-43484
Has anyone been able to find a fix for CVE-2024-43484? I have a vulnerable file version here: C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\System.io.compression.dll has version 4.8.9221.0. KB5066131 's file information csv shows that this file gets updated to version 4.8.9277.0 but the machines won't accept the KB to install it. I did also try looking for the latest KB that superseded it which is as of this post Septembers KB5126052 however, when I look at the file information csv for KB5126052 it shows this file back to the old version at 4.8.9221.0. What gives? Did Microsoft update this file and then revert it in later KB or is it just a mistake? Is there any fix?CVE-2024-43484
Has anyone been able to remediate CVE-2024-43484? I do actually see the vulnerable file version on machines in this location: C:\WINDOWS\Microsoft.NET\Framework64\v4.0.30319\System.io.compression.dll has version 4.8.9221.0. Okay, so I download KB5066131 which says in it's file information csv that it updates this .dll to file version 4.8.9277.0. I try to install it and get a message that the KB is not applicable to my system. I run the commands to extrand the .cab file then install it with DISM and reboot the machine...but the file version doesn't update. So I look at the latest KB that superceeded KB5066131which is as of today september's KB5126052 but when you look at the listed file information csv it says it reverts this file back to version 4.8.9221.0. I'm so confussed now. Was this a Microsoft mistake or is there an actual fix to this?
What I Learned Contributing to .NET Runtime #135120 — Why More Developers Should Try Open Source
Contributing to the .NET Runtime was something I had wanted to try for a long time. Recently, I opened PR #135120 in the dotnet/runtime repository. https://github.com/dotnet/runtime/pull/135120 What surprised me most was not just the code change, but the engineering process behind making even a focused change in a large, production-grade open-source project. WHAT I LEARNED 1. Reading source code is a skill Before changing anything, I had to understand how the existing implementation worked and how the surrounding code was designed. 2. Tests tell a story Existing tests helped me understand the expected behavior and gave me confidence that the change was not breaking existing scenarios. 3. Small changes can require deep investigation A change that looks small from the outside can involve understanding implementation details, existing conventions, edge cases, and compatibility considerations. 4. Code review is part of the learning process A pull request is not simply code submitted for approval. It is an opportunity to learn from developers who know the codebase extremely well. 5. You do not have to be an expert before contributing This has probably been my biggest takeaway. I used to think I needed to understand the entire .NET Runtime before contributing to it. I don't. You can start with one problem, investigate it deeply, and learn along the way. MY QUESTION FOR THE .NET COMMUNITY For developers who have contributed to .NET, ASP.NET Core, EF Core, or other major open-source projects: What was your first contribution, and what did it teach you that you would not have learned from building your own applications? I would love to hear your experiences and advice for developers who are considering their first open-source contribution.

Not sure what is going on ... (happened after VS update)Need help with ClickOnce deployment on .NET Framework 4.7.2 – "Unidentified program" warning
Hello, I have a WinForms application built on .NET Framework 4.7.2 that I'm publishing using ClickOnce from Visual Studio Community 2022 (official Microsoft version). Even after signing the application with a valid SHA256 V3 self-signed certificate, when I publish and try to install it via ClickOnce, I receive a warning saying the program is unidentified. Additionally, when I try to install the application on a machine that has antivirus software, the antivirus flags the program precisely because of the missing/certificate validation issue. How should I proceed? I'd like to know the correct way to publish with ClickOnce so that the application is fully recognized as valid by Windows, since I'm running into these antivirus validation problems. Thanks in advance for any guidance!
