Synopsis:          Important: nss, nss-util, and nss-softokn security, bug fix, and enhancement update
Advisory ID:       SLSA-2014:1948-1
Issue Date:        2014-12-02
CVE Numbers:       CVE-2014-3566
--

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.

The nss, nss-util, and nss-softokn packages have been upgraded to upstream
version 3.16.2.3, which provides a number of bug fixes and enhancements
over the previous version, and adds the support for Mozilla Firefox 31.3.

After installing this update, applications using NSS or NSPR must be
restarted for this update to take effect.
