Uns erreichte im Rahmen unserer Red Hat Enterprise Network Mitgliedschaft die nachfolgend aufgeführte Originalmeldung. Sämtliche betroffenen Server wurden von uns mit dem Sicherheitsupdate ausgestattet und betroffene Dienste im Rahmen des Updates neu gestartet. "Important: openssl security update

Updated openssl packages that fix one security issue are now available for Red Hat Enterprise Linux 6.

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.

Description:

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. 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."
