** Description changed:
+ [ Impact ]
+
+ GTK crashes when processing some invalid AT-SPI method calls.
+
+ One way this manifests is when opening the System > About page in the
+ Settings app, while the Desktop Zoom accessibility feature is enabled.
+
+ [ Test Plan ]
+
+ 1. Launch the Settings app
+ 2. Navigate to Accessibility > Zoom
+ 3. Enable Desktop Zoom
+ 4. Navigate to System > About
+ 5. Verify that the Settings application did not crash
+
+ [ Where problems could occur ]
+
+ GTK4 is the graphical toolkit used to build applications, most often used by
GNOME applications. Problems would manifest in any application using GTK4.
+ However, the patch is only adding some defensive checks to protect against
invalid parameters in the AT-SPI DBus method calls.
+
