[arch-announce] openssh-7.0p1 deprecates ssh-dss keys

In light of recently discovered vulnerabilities, the new `openssh-7.0p1` release
deprecates keys of `ssh-dss` type, also known as DSA keys. See the [upstream
announcement][1] for details.

Before updating and restarting `sshd` on a remote host, make sure you do not
rely on such keys for connecting to it. To enumerate DSA keys granting access to
a given account, use:


grep ssh-dss ~/.ssh/authorized_keys


If you have any, ensure you have alternative means of logging in, such as key
pairs of a different type, or password authentication.

Finally, host keys of `ssh-dss` type being deprecated too, you might have to
confirm a new fingerprint (for a host key of a different type) when connecting
to a freshly updated server.
