    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.
    Debian GNU/Linux 2.2 alias potato
