Summary
[none]
Details

The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using gfilemakedirectorywithparents (kfsb->dir, NULL, NULL) and files using gfilereplacecontents (kfsb->file, contents, length, NULL, FALSE, GFILECREATEREPLACEDESTINATION, 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.
