1084875: CVE-2014-0160 openssl: information disclosure in handling of TLS heartbeat extension packets
An information disclosure flaw was found in the way OpenSSL handled TLS and DTLS Heartbeat Extension packets. A malicious TLS or DTLS client or server could send a specially crafted TLS or DTLS Heartbeat packet to disclose a limited portion of memory per request from a connected client or server. Note that the disclosed portions of memory could potentially include sensitive information such as private keys.
