As far as I know bug affects applications where TLS is talked on the
wire by OpenSSL.

I believe OpenSSH just used crypto functions from openssl, and so is
probably not vulnerable, but open to correction by anyone whose read the
source carefully enough to say otherwise.

I've been patching today, and some cases restarting services to avoid
reboots.

The command:

grep deleted /proc/*/maps

Will show running programs depending on deleted shared libraries. Which
you'll want if you didn't reboot. Debian supposedly handles this more
gracefully, but Ubuntu quite happily carried on running the old OpenSSL
version.

Using this I've seen Web servers (Apache/Nginx), XMPP servers (prosody),
Mail servers (sendmail and Postfix), whoopsie (yes clients might be
affected too), yum-updatesd, and OpenVPN as likely to be impacted.

Easiest is patch and reboot.
