The remote host is missing an update to joe announced via advisory DSA 003-1.
The security fix for joe released on November 22, 2000 had a problem: it created the DEADJOE file securily but didn't write anything to it. This has been fixed in version 18.104.22.168 . This is the text from the previous advisory: 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.
