TITLE:
GNU nano Two Security Issues

SECUNIA ADVISORY ID:
SA39444

VERIFY ADVISORY:
http://secunia.com/advisories/39444/

DESCRIPTION:
Some security issues have been reported in GNU nano, which can be
exploited by malicious, local users to perform certain actions with
escalated privileges.

1) The application does not properly verify if the file currently
being edited has been changed outside the context of the current
editing session before writing to it, which can be exploited to e.g.
overwrite arbitrary files via symlink attacks.

2) A race condition exists when creating backup files, which can be
exploited to take the ownership of arbitrary files via e.g. symlink
attacks.

Successful exploitation requires that the victim is tricked into
editing files owned by the attacker and that the backup functionality
is enabled.

SOLUTION:
Update to version 2.2.4.
