  script_tag(name:"insight", value:"OpenSSL is a toolkit that implements
the Secure Sockets Layer (SSL), Transport Layer Security (TLS), and Datagram
Transport Layer Security (DTLS) protocols, as well as a full-strength, general
purpose cryptography library.

This update adds support for the TLS Fallback Signaling Cipher Suite Value
(TLS_FALLBACK_SCSV), which can be used to prevent protocol downgrade
attacks against applications which re-connect using a lower SSL/TLS
protocol version when the initial connection indicating the highest
supported protocol version fails.

This can prevent a forceful downgrade of the communication to SSL 3.0.
The SSL 3.0 protocol was found to be vulnerable to the padding oracle
attack when using block cipher suites in cipher block chaining (CBC) mode.
This issue is identified as CVE-2014-3566, and also known under the alias
POODLE. This SSL 3.0 protocol flaw will not be addressed in a future
update  it is recommended that users configure their applications to
require at least TLS protocol version 1.0 for secure communication.

For additional information about this flaw, see the Knowledgebase article
linked at the references.

All OpenSSL users are advised to upgrade to these updated packages, which
contain a backported patch to mitigate the CVE-2014-3566 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.");
