"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.
(CVE-2014-0160)

For the update to take effect, all services linked to the OpenSSL
library (such as httpd and other SSL-enabled services) must be
restarted or the system rebooted.");
