THIS APPLIES TO BOTH SERVERS AND CLIENTS
Howdy,
All services that implement the official Bitcoin Core and Electrum could also be susceptible to "heartbleed" as it also implements OpenSSL.
Any application that could potentially use or implement the vulnerable OpenSSL libraries is liable to being vulnerable to "heartbleed".
I highly urge everyone to update to the latest Bitcoin 0.9.1 core.
Anyone running Electrum from python source, please make sure your system is not using an affected OpenSSL package. For users running the Electrum binaries straight from Electrum, you are safe; the binaries are built with OpenSSL 0.9.8.
Everyone please be safe and check if your applications are using any of the OpenSSL libraries that the application itself is also not vulnerable.

If there are any questions or feedback, please feel free to contact us on BlackBank at any time or share on our forums.
Cheers,
MDParity
note: all that the Bitcoin project done was download the latest version of openssl and re-build their downloads. If you are not using a statically linked version of Bitcoin then your system update would suffice
This is exactly why we have libraries and dynamic linking, so that when you need to upgrade you only have one place to do it rather than updating every. single. application.
