.NET Remote Code Execution Vulnerability

  • Disclosed: 18.10.2022
  • Updated: 11.10.2026 11:23

Microsoft is releasing this security advisory to provide information about a vulnerability in .NET 6.0, .NET 5.0, and .NET Core 3.1. This advisory also provides guidance on what developers can do to update their applications to remove this vulnerability. A Remote Code Execution vulnerability exists in .NET 6.0, .NET 5.0, and .NET Core 3.1 where a stack buffer overrun occurs in .NET Double Parse routine.

Patches

  • Any .NET 6.0 application running on .NET 6.0.2 or lower
  • Any .NET 5.0 application running on .NET 5.0.14 or lower
  • Any .NET Core 3.1 application running on .NET Core 3.1.22 or lower

To fix the issue, please install the latest version of .NET 6.0, .NET 5.0, or .NET Core 3.1. If you have installed one or more .NET Core SDKs through Visual Studio, Visual Studio will prompt you to update Visual Studio, which will also update your .NET Core SDKs.

  • If you're using .NET 6.0, you should download and install Runtime 6.0.3 or SDK 6.0.103 (for Visual Studio 2019 v17.0) or SDK 6.0.201 (for Visual Studio 2019 V17.1) from https://dotnet.microsoft.com/download/dotnet-core/5.0.
  • If you're using .NET 5.0, you should download and install Runtime 5.0.15 or SDK 5.0.406 (for Visual Studio 2019 v16.11) or SDK 5.0.212 (for Visual Studio 2019 V16.9) from https://dotnet.microsoft.com/download/dotnet-core/5.0.
  • If you're using .NET Core 3.1, you should download and install Runtime 3.1.23 or SDK 3.1.417 (for Visual Studio 2019 v16.7) from https://dotnet.microsoft.com/download/dotnet-core/3.1. .NET 6.0, .NET 5.0, and .NET Core 3.1 updates are also available from Microsoft Update.
