Debian 2.2 DSA-004-1 Critical: Nano Symlink Attack Mitigation

- ------------------------------------------------------------------------ Debian Security Advisory
When nano (a free pico clone) unexpectedly diesit tries a warning message to a new file with a predictable name.

Summary

Package : nano
Problem type : symlink attack
Debian-specific: no

The problem that was previously reported for joe also occurs with
other editors. When nano (a free pico clone) unexpectedly dies
it tries a warning message to a new file with a predictable name
(the name of the file being edited with ".save" appended). Unfortunately
that file was not created safely which made nano vulnerable to a
symlink attack.

This has been fixed in version 0.9.23-1 (except for powerpc, which has
version 0.9.23-1.1).

wget url
will fetch the file for you
dpkg -i file.deb
will install the referenced file.
