Only 1.0.1 and 1.0.2-beta releases of OpenSSL are affected including 1.0.1f and 1.0.2-beta1.


1. Does DeviceLock utilize OpenSSL?

2. If true, can this be a threat?


1. Yes, it does.

2. No, it cannot: older versions of DeviceLock utilize a non vulnerable older version of OpenSSL, while current versions of DeviceLock (7.3.x) utilize OpenSSL 1.0.1e with TLS heartbeat extension specifically deactivated.

Also DeviceLock builds with version number higher than 7.3.55818 utilize OpenSSL 1.0.1g.
