.NET Framework August 2022 Security and Quality Rollup Updates

Salini Agarwal

Yesterday, we released the August 2022 Security and Quality Rollup Updates for .NET Framework.

Security

The August Security and Quality Rollup Update does not contain any new security fixes. See May 2022 Security and Quality Rollup for the latest security updates.

Quality and Reliability

This release contains the following quality and reliability improvements.

Networking
  • Addresses an issue when Ssl negotiation can hang indefinitely when client certificates are used when TLS 1.3 is negotiated. Before the change renegotiation (PostHandshakeAuthentiction) would fail and SslStream or HttpWebRequest would observe timeout. Possible workaround is disabling TLS 1.3 either via Switch.System.Net.DontEnableTls13 AppContext or via OS registry.
WPF1
  • Addresses an issue where invoking a synchronization Wait on the UI thread can lead to a render-thread failure, due to unexpected re-entrancy.
