  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.

It was found that NSS permitted skipping of the ServerKeyExchange packet
during a handshake involving ECDHE (Elliptic Curve Diffie-Hellman key
Exchange). A remote attacker could use this flaw to bypass the
forward-secrecy of a TLS/SSL connection. (CVE-2015-2721)

A flaw was found in the way NSS verified certain ECDSA (Elliptic Curve
Digital Signature Algorithm) signatures. Under certain conditions, an
attacker could use this flaw to conduct signature forgery attacks.
(CVE-2015-2730)

Red Hat would like to thank the Mozilla project for reporting this issue.
Upstream acknowledges Karthikeyan Bhargavan as the original reporter of
CVE-2015-2721, and Watson Ladd as the original reporter of CVE-2015-2730.

The nss packages have been upgraded to upstream version 3.19.1, which
provides a number of bug fixes and enhancements over the previous version.

All nss users are advised to upgrade to these updated packages, which
correct these issues.");
