OpenURL() in usersession/userd/launcher.go would alter $XDG_DATA_DIRS to append a path to a directory controlled by the calling snap. A malicious snap could exploit this to bypass intended access restrictions to control how the host system xdg-open script opens the URL and, for example, execute a script shipped with the snap without confinement. This issue did not affect Ubuntu Core systems. Fixed in snapd versions 2.45.1ubuntu0.2, 2.45.1+18.04.2 and 2.45.1+20.04.2."},{"lang":"es","value":"Se detectó que snapctl user-open permitía alterar la variable de entorno $XDG_DATA_DIRS cuando se llama al sistema xdg-open. La función OpenURL() en el archivo usersession/userd/launcher.go alteraría $XDG_DATA_DIRS para agregar una ruta a un directorio controlado por el complemento de llamada. Un complemento malicioso podría explotar esto para omitir las restricciones de acceso previstas para controlar cómo el script xdg-open del sistema host abre la URL y, por ejemplo, ejecuta un script enviado con el complemento sin confinamiento.
