Impact: Low Public Date: 2019-06-28 CWE: CWE-732 Bugzilla: 1728632: CVE-2019-13012 glib2: insecure permissions for files and directories The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.59.1 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.
