The remote Red Hat host is missing one or more security updates.
Updated openssl packages that fix one security issue are now available
for Red Hat Enterprise Linux 5.
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.
It was found that OpenSSL clients and servers could be forced, via a
specially crafted handshake packet, to use weak keying material for
communication. A man-in-the-middle attacker could use this flaw to
decrypt and modify traffic between a client and a server.
Note: In order to exploit this flaw, both the server and the client
must be using a vulnerable version of OpenSSL
the server must be
using OpenSSL version 1.0.1 and above, and the client must be using
any version of OpenSSL. For more information about this flaw, refer
Red Hat would like to thank the OpenSSL project for reporting this
issue. Upstream acknowledges KIKUCHI Masashi of Lepidum as the
original reporter of this issue.
All OpenSSL users 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
