OpenSSL’s TLS implementation before 1.0.1g fails to handle Heartbeat Extension packets properly, allowing attackers to read sensitive information from process memory using crafted packets.


Upgrade to OpenSSL 1.0.1g or later. Reissue HTTPS certificates and replace compromised asymmetric private keys, shared secret keys with no evidence of compromise in server logs.
