August 2021 .NET Updates

[TaraOverfield]

The following .NET updates were released in August 2021. This issue will be updated if there are any additional releases during the month.

.NET

• .NET August 2021 Updates – 5.0.9, 3.1.17 and 2.1.29
  • .NET 5.0.9 and .NET SDK 5.0.400, .NET SDK 5.0.302 and .NET SDK 5.0.205 (Release Notes | Download)
  • .NET Core 3.1.18 and .NET SDK 3.1.412 and NET SDK 3.1.118 (Release Notes | Download)
  • .NET Core 2.1.30 and .NET SDK 2.1.526 and NET SDK 2.1.818 (Release Notes | Download)

Update 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.
