JSON

The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0
creates directories using g_file_make_directory_with_parents (kfsb->dir,
NULL, NULL) and files using g_file_replace_contents (kfsb->file, contents,
length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL).
Consequently, it does not properly restrict directory (and file)
permissions. Instead, for directories, 0777 permissions are used; for
files, default file permissions are used. This is similar to
CVE-2019-12450.
