Heartbleed OpenSSL vulnerability
This vulnerability means that your system is running a vulnerable version of openssl that is vulnerable to the Heartbleed Vulnerability. This vulnerability makes it possible for an attacker to steal information from memory on your server, remotely, including passwords, sensitive information and private SSL keys. This is a very serious vulnerability and means that TLS and SSL based connections on your system can be compromised by an attacker exposing any information being sent over these connections.
Next Steps
Step 1) Patch OpenSSL
To fix this vulnerability you need to upgrade openssl to a version that is not vulnerable to this hole. The follow list provides links to specific vendors websites with instructions to fix this vulnerability.
Redhat: https://access.redhat.com/security/cve/CVE-2014-0160
Centos: See the Redhat information above. Centos is a derivative of RHEL.

Step 2) Restart all services that use SSL
The follow is a partial list of all services that may use SSL
- http/apache
- http/nginx
- http/litespeed
- IMAP/POP servers
- SMTP mail servers
- control panels
- file sharing applications
- FTP (if configured to use SSL)
Note: SSH does not use SSL
Step 3) Rekey your servers
Because heartbleed can make it possible for an attacker to steal your private keys, it is recommended that your re-key your servers. Please contact your CA vendor for specific instructions to do this, as each CA vendor may have a different process.
Step 4) Optional: Add defense in depth to TLS to help mitigate potential future vulnerabilities
It is also recommended that you implement Perfect Forward Secrecy on your server to mitigate possible future vulnerabilities in the TLS protocol. Please see the PFS article for recommendations.
