NO, this is not a duplicate of How to patch the Heartbleed bug (CVE-2014-0160) in OpenSSL?. So, read on.

I am seeing conflicting information with respect to Ubuntu 12.04:


The Heartbleed page claims Ubuntu 12.04 to be affected and needs to be patched with 1.0.1g
The Ubuntu Security Notice USN-2165-1 claims that version 1.0.1-4ubuntu5.12 for the package libssl1.0.0 should fix the issue on Ubuntu 12.04.


Now I do have these packages installed:

# dpkg -l | grep ssl
ii  libssl1.0.0                      1.0.1-4ubuntu5.10                 SSL shared libraries
ii  openssl                          1.0.1-4ubuntu5.10                 Secure Socket Layer (SSL) binary and related cryptographic tools

# lsb_release  -a | grep -i description
Description:    Ubuntu 12.04.3 LTS


So, If I consider above two points, I am not sure which one is true.

Besides, this Heartbleed test page says that my machine is vulnerable.

Has anyone yet been able to fix this issue successfully on Ubuntu 12.04? If yes, then could you provide me the steps you have taken?


Question: What happened to my KDE task bar? How can I get it back?
Answer: It sounds like you somehow got the KDE "netbook" interface, assuming it looks like this:

You can switch the workspace under System Settings -> Workspace -> workspace type; set it to "desktop".  Here's a screenshot:
