ssh-host-config eval password bug

Reply to Author | View in Thread

In the ssh package there is a bug in /usr/bin/ssh-host-config where if you
select a valid password spaces or punctuation that bash knows of, it will
fail and you could possibly shoot yourself in the foot due to evaling your
password. I don't know who is responsible, or what mailing list to post on,
but here is a patch.
