We recommend that you upgrade your openssl packages.  Note that services
linking against the openssl shared libraries will need to be restarted.
Common examples of such services include most Mail Transport Agents, SSH
servers, and web servers.

Upgrade Instructions
- --------------------

wget url
       will fetch the file for you
dpkg -i file.deb
       will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
       will update the internal database
apt-get upgrade
       will install corrected packages
