Heartbleed OpenSSL Vulnerability (Indicative)

Summary

The TLS and DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, allowing remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, potentially disclosing sensitive information.

Solution

Update to OpenSSL 1.0.1g or later. Re-issue HTTPS certificates. Change asymmetric private keys and shared secret keys, since these may have been compromised, with no evidence of compromise in the server log files.
