The .NET Core 2.1.29 August update did not include the correct fix for CVE-2021-34532. To resolve this, we are re-releasing the August security update for .NET Core 2.1 as 2.1.30. If you have installed .NET Core 2.1.29 previously you need to install the .NET Core 2.1.30 update in order to be fully protected.
_Note: .NET Core 3.1 and .NET 5.0 August updates are not affected and therefore not being re-released._
As a reminder and identified in the .NET Core and .NET 5 Support Policy, at the end of this month (August 2021), .NET Core 2.1 runtime will be out of support and after this time we will no longer be providing fixes, updates, or online technical assistance for this version. For those customers who are using the ASP.NET Core 2.1 packages on .NET Framework, this continues to be a supported scenario, as you are running on the .NET Framework runtime and not .NET Core 2.1. For development using this scenario going forward, however, you will need to be using the latest .NET SDK and Visual Studio. As a reminder, the list of Packages that are covered by this scenario are available here: ASP.NET Core 2.1 Supported Packages and apply only to running on the .NET Framework.
