Descriptions

file_copy_fallback in gio/gfile.c in GNOME GLib 2.15.0 through 2.61.1 does not properly restrict file permissions while a copy operation is in progress. Instead, default permissions are used.

La función file_copy_fallback en el archivo gio/gfile.c en GNOME GLib versión 2.15.0 hasta la 2.61.1, no restringe apropiadamente los permisos de los archivos durante una operación de copia en progreso. En su lugar, se utilizan los permisos por defecto.
