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.
