Important OpenSSL Security Update: CVE-2014-0160 (Heartbleed)

Published 2014-04-08T03:20:42+00:00

Overview

An information disclosure flaw was found in the way OpenSSL handled transport layer security (TLS) and datagram transport layer security (DTLS) Heartbeat Extension packets. This flaw is commonly referred to as the Heartbleed bug.

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)

This issue did not affect the versions of OpenSSL as shipped with Red Hat Enterprise Linux 5, Red Hat Enterprise Linux 6.4 and earlier and Red Hat Enterprise Linux 7. This issue does affect Red Hat Enterprise Linux 7 beta, Red Hat Enterprise Linux 6.5, Red Hat Enterprise Virtualization Hypervisor 6.5, and Red Hat Storage 2.1, which provided OpenSSL 1.0.1e.

Once you have updated your systems, you can use Red Hat's Heartbleed Detector to validate your systems have been secured. Reports from the security research community have now proven that private keys may be stolen from vulnerable systems. Red Hat strongly recommends that customers assess the risk this may pose to their systems and react accordingly (for example, by replacing SSL keys). For more information on this, please read Recovering from the Heartbleed Vulnerability.
