The Heartbleed Bug is a serious vulnerability in the popular OpenSSL as such we recommend you patch your server immediately, this will require a quick reboot once done. Please follow the steps below to apply the necessary patch.
For all managed server customers this is being done automatically for you.
What is it?
This is a serious vulnerability in the popular OpenSSL cryptographic software library. This weakness allows stealing the information protected, under normal conditions, by the SSL/TLS encryption used to secure the Internet. SSL/TLS provides communication security and privacy over the Internet for applications such as web, email, instant messaging (IM) and some virtual private networks (VPNs).
The Heartbleed bug allows anyone on the Internet to read the memory of the systems protected by the vulnerable versions of the OpenSSL software. This compromises the secret keys used to identify the service providers and to encrypt the traffic, the names and passwords of the users and the actual content. This allows attackers to eavesdrop on communications, steal data directly from the services and users and to impersonate services and users.
How to stop the leak?
As long as the vulnerable version of OpenSSL is in use it can be abused. Fixed OpenSSL has been released and now it has to be deployed. Operating system vendors and distribution, appliance vendors, independent software vendors have to adopt the fix and notify their users. Service providers and users have to install the fix as it becomes available for the operating systems, networked appliances and software they use.
How do I fix the vulnerability?
Remediation of exposed servers
For Debian/Ubuntu servers:
apt-get update and apt-get upgrade
For RHEL/CentOS based servers:
yum update and yum upgrade
Here are the links with the release notes that contain the package names of the fixed versions:
For any customers running cpanel Cpanel/WHM repos have an updated openssl too so simply run update from within WHM.
Run Update System Software under the Software heading in WHM
Windows servers - IIS is not vulnerable as it does not use the OpenSSL library
