The g_file_copy function in glib 2.0 sets the permissions of a target file to the permissions of a symbolic link (777), which allows user-assisted local users to modify files of other users, as demonstrated by using Nautilus to modify the permissions of the user home directory.
The product specifies permissions for a security-critical resource in a way that allows that resource to be read or modified by unintended actors.
