The Heartbleed Bug

We recently learned about a serious vulnerability in OpenSSL Certificates, known as the Heartbleed Bug. This vulnerability has existed for more than two years and compromises the security of passwords, credit cards, and other sensitive information. Since this has widespread implications on the Internet, we wanted to inform you of this issue and assure you that most of the hosting and server companies make every effort to keep their systems patched to limit the impact of security vulnerabilities. Updates have been made to our systems to ensure that we remain unaffected by this vulnerability.

If you have any questions, please contact our support team

The Heartbleed Bug 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 impersonate services and users.

What leaks in practice?

We have tested some of our own services from the attacker’s perspective. We attacked ourselves from outside, without leaving a trace. Without using any privileged information or credentials we were able to steal from ourselves the secret keys used for our X.509 certificates, user names and passwords, instant messages, emails, and business-critical documents and communication.

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.
