Descriptions

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.

La back-end de configuración de keyfile en GLib (también se conoce como glib2.0) anterior a versión 2.60.0 de GNOME, crea directorios usando g_file_make_directory_with_parents (kfsb-)dir, NULL, NULL) y archivos utilizando g_file_replace_contents (kfsb-)file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL). En consecuencia, no restringe apropiadamente los permisos de directorio (y archivo). En cambio, para los directorios, son usados permisos 0777; para los archivos, se utilizan permisos de archivo por defecto. Esto es similar a CVE-2019-12450.
