Scientific Linux Security Update : openssl on SL5.x i386/x86_64 (POODLE)

This script is Copyright (C) 2014-2016 Tenable Network Security, Inc.


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

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 Upstream's
Knowledgebase article at https://access.redhat.com/articles/1232123

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.
