      bypasses the security checks in the affected .NET versions, potentially
      leading to unauthorized access or data manipulation.
  * d/p/0002-roslyn-analyzers-dont-use-apphost.patch: refreshed patch to fix
    hunk failure.

      name.

  * d/rules: cleaned up trailing spaces.
  * d/eng/test-runner: removed unnecessary files from source tree.

    source package.
