  "details": "Updated lightdm-gtk-greeter package fixes security vulnerability:\n\nlightdm-gtk-greeter uses the lightdm-gobject API incorrectly and does not\nhandle lightdm_greeter_get_authentication_user() returning NULL when the\nusername of the previous authentication is invalid resulting in a NULL pointer\ndereference in start_authentication(). This constitutes a local denial of\nservice which can be triggered by any unprivileged attacker requiring the\nintervention of an administrator to restart lightdm (CVE-2014-0979).\n",
