    Package        : joe
    Problem type   : symlink attack
    Debian-specific: no
    When joe (Joe's Own Editor) dies due to a signal instead of a normal
    exit it saves a list of the files it is editing to a file called `DEADJOE'
    in its current directory. Unfortunately this wasn't done safely which made
    joe vulnerable to a symlink attack.
    This has been fixed in version 2.8-15.1 .
    wget url
            will fetch the file for you
    dpkg -i file.deb
            will install the referenced file.
