changes of ownerships of important files.

Background
=========
nano is a GNU GPL'd Pico clone with more functionality.

Affected packages

    -------------------------------------------------------------------
     Package           /  Vulnerable  /                     Unaffected

Description
==========
Multiple race condition vulnerabilities have been discovered in nano.
For further information please consult the CVE entries referenced
below.

Impact
=====
Under certain conditions, a local, user-assisted attacker could
possibly overwrite arbitrary files via a symlink attack on an
attacker-owned file that is being edited by the victim, or change the
ownership of arbitrary files.

Workaround
