I've read the news early.

Lucky for me, my own servers weren't affected, since I used a libssl
version there that did not support heartbeat.

I've read the advisory and can confirm that it affects apache2 & co.,
i.e. all included servers that use libssl1.0.0 (which is actually
version 1.0.1e) on Knoppix versions not older than 2 years; only IF
these servers are started, of course. As far as I read from the
advisory, client programs like browser or ssh are not affected because
it is the server side that leaks 64k of memory to a specially crafted
heartbeat client request, so online banking or shopping with Knoppix
should still be safe. Of course I will update libssl in the next public
release anyways.

wpa_supplicant on Knoppix, btw, was using libtls instead of openssl due
to a bug in openssl that kept eduroam (frequentl used in german
universities) from functioning correctly, so the network-manager was not
affected at all in Knoppix. I will check if the new version of libssl
has also fixed this issue and revert to the original debian
wpa_supplicant if it is the case (don't like forking essential

As a quick fix for ssl servers, when using the current version of
Knoppix installed on USB flash disk (as recommended), doing an update of
libssl1.0.0 will replace libssl1.0.0 with the bugfixed 1.0.1g version
from Debian:

sudo apt-get update
sudo apt-get install -t unstable libssl1.0.0

(no need to replace all the servers that use libssl).
