The problem can be corrected by upgrading your system to the following package versions: Ubuntu 8.04 LTS: libglib2.0-0 2.16.6-0ubuntu1.2 Ubuntu 8.10: libglib2.0-0 2.18.2-0ubuntu2.2 Ubuntu 9.04: libglib2.0-0 2.20.1-0ubuntu2.1 After a standard system upgrade you need to restart your session to effect the necessary changes. Details follow: Arand Nash discovered that applications linked to GLib (e.g. Nautilus) did not correctly copy symlinks. If a user copied symlinks with GLib, the symlink target files would become world-writable, allowing local attackers to gain access to potentially sensitive information. (Distributions)
