DD-WRT is a Linux based alternative OpenSource firmware suitable for a great variety of WLAN routers and embedded systems. The main emphasis lies on providing the easiest possible handling while at the same time supporting a great number of functionalities within the framework of the respective hardware platform used.
The Heartbleed vulnerability in discovered in OpenSSL 1.0.1 - 1.0.1f is one of the most serious matters in encrypted data communication during the last years. First of all we can ensure you that the encrypted web services like the DD-WRT Online Shop and the Activation center never have been affected because the OpenSSL version we are using does not contain the vulnerability.
Currently the main focus of the Heartbleed discussion lies on web servers using SSL/TLS but other services on Linux systems are also using OpenSSL. By default none of these services is enabled in DD-WRT - nevertheless it is important that you check your router settings to find out if you might be affected by Heartbleed.
