+Subject: [PATCH] gfile: Limit access to files when copying
+
+file_copy_fallback creates new files with default permissions and
+set the correct permissions after the operation is finished. This
+might cause that the files can be accessible by more users during
+the operation than expected. Use G_FILE_CREATE_PRIVATE for the new
+files to limit access to those files.
+
+Upstream-Status: Backport
