Package        : openssh
Problem type   : remote exploit
Debian-specific: no

The adv.fwd security advisory from OpenBSD reported a problem
with openssh that Jacob Langseth <jwl@pobox.com> found: when
the connection is established the remote ssh server can force
the ssh client to enable agent and X11 forwarding.

This has been fixed in version 1.2.3-9.1 and we recommend
that you upgrade your openssh packages immediately.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.
