Hello,
This week is going to be quite interesting...
Now that the word has been released it will be a world wide a race between
the Hackers and the Sys Admins trying to fix this nasty "Heart Bleed"
libSSL bug before too much "cloud data" get stolen & users get very upset.
Please consider updating asap libSSL to version 1.0.1g, cf: CVE-2014-0160

Greetings, Gilles.

Thanks for the warning.

FYI, reloading Synaptic on Knoppix 7.2 gives only an upgrade to 1.0.1e2,
which your references say is still vulnerable.

How would inexpert users like myself bring in libSSL 1.0.1g?

Also, for information, if users like myself are only using the stock
Knoppix LiveUSB with no additional ports left open, might this precaution
be unnecessary?

Starting Nmap 6.00 ( http://nmap.org ) at 2014-04-09 10:57 UTC
Nmap scan report for 192.168.1.3
Host is up (0.00057s latency).
All 1000 scanned ports on 192.168.1.3 are closed

Nmap done: 1 IP address (1 host up) scanned in 0.11 second

Thanks & Best Regards.

Hi Utu,
As always there are more than one way to solve a problem.
To patch your setup with synaptic (as root) you need to:
1) Reload package information (under the edit menu)
2) Search for "libSSL" and select (left click) on "libssl1.0.0"
3) Choose "force version" (under the edit menu) and select "1.0.1g-2 (testing)"
4) Apply button after accept & confirm the changes ("Mark", "Ok" & "Forward" buttons)
5) Check the libSSL "g" version: using: "openssl version"
OpenSSL 1.0.1c 10 May 2012 (Library: OpenSSL 1.0.1g 7 Apr 2014)
Hope this helps,
Best Regards,
Gilles

PS: This vulnerability is really an serious issue for the servers using SSL
(as the web server Apache) and which are connected to the public Internet.

3) Choose "force version" (under the edit menu) and select "1.0.1g-2 (testing)"

Thanks, Gilles. This worked like a charm.

knoppix@Microknoppix:~$ openssl version 
OpenSSL 1.0.1e 11 Feb 2013 (Library: OpenSSL 1.0.1g 7 Apr 2014)

I got this probably since I upgrated to g1 first, then g2.

This vulnerability is really an serious issue for the servers using SSL
(as the web server Apache) and which are connected to the public Internet.

I hope nobody will do this with Knoppix. If you want to offer services like for example Apache, Exim and so on you cannot use a LiveCD like Knoppix for this.

In using Knoppix to make internet contact with sites such as
Amazon or Yahoo, I may transmit private information, expecting
the communication is secure using the https protocol to
communicate.

Does my OS's implementation of SSL make any difference
in the security of this communication or is it only the
SSL implementation of the https site that is important?

[Werner P. Schulz]

If you communicate with Amazon or Yahoo you are on the client side, not the server.

But you should change your password as soon as possible and never use the same password for different connections, email and so on.
