  script_tag(name:"insight", value:"Network Security Services (NSS) is a set
  of libraries designed to support cross-platform development of security-enabled
  client and server applications.

A flaw was found in the way the TLS protocol composes the Diffie-Hellman
(DH) key exchange. A man-in-the-middle attacker could use this flaw to
force the use of weak 512 bit export-grade keys during the key exchange,
allowing them do decrypt all traffic. (CVE-2015-4000)

Note: This update forces the TLS/SSL client implementation in NSS to
reject DH key sizes below 768 bits, which prevents sessions to be
downgraded to export-grade keys. Future updates may raise this limit to
1024 bits.

The nss and nss-util packages have been upgraded to upstream versions
3.19.1. The upgraded versions provide a number of bug fixes and
enhancements over the previous versions.

Users of nss and nss-util are advised to upgrade to these updated packages,
which fix these security flaws, bugs, and add these enhancements.");
