.NET Framework November 2022 Security and Quality Rollup Updates

Salini Agarwal

Today, we are releasing the November 2022 Security and Quality Rollup Updates for .NET Framework.


CVE-2022-41064– .NET Framework Information Disclosure Vulnerability

This security update addresses a vulnerability which exists in System.Data.SqlClient and Microsoft.Data.SqlClient libraries where a timeout occurring under high load can cause incorrect data to be returned as the result of an asynchronously executed query or command.

Quality and Reliability

  • Addresses an issue where a FailFast crash could occur when using WebBrowser.NavigateToString.
  • Addresses an ArgumentOutOfRangeException that can arise when calling ListBox.ScrollIntoView while there are pending changes to the visual tree that will change or clear the underlying ItemsCollection.
  • Addresses an ArgumentException “Width and Height must be non-negative” that can arise in an ItemsControl with grouping enabled, custom margins on the GroupItems, collapse/expand of GroupItems enabled, and run in high-DPI.
  • Addresses an issue where the opt-out switch Switch.System.Windows.Controls.ToolTip.OptOutOfWCAG21ToolTipBehavior didn’t quite restore the 4.8 behavior, in particular the way it honors Switch.UseLegacyToolTipDisplay (which controls whether keyboard tooltip behavior is enabled).
.NET Runtime
  • Address crashes that could occur if ilasm.exe failed to establish temporary PDB file alongside the output file.
