"Updated openssl packages that fix one security issue are now available
for Red Hat Storage 2.1.

The Red Hat Security Response Team has rated this update as having
Important security impact. A Common Vulnerability Scoring System
(CVSS) base score, which gives a detailed severity rating, is
available from the CVE link in the References section.

OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL
v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a
full-strength, general purpose cryptography library.

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)

Red Hat would like to thank the OpenSSL project for reporting this
issue. Upstream acknowledges Neel Mehta of Google Security as the
original reporter.

All users of Red Hat Storage are advised to upgrade to these updated
packages, which contain a backported patch to correct this issue. 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.");
