Synopsis :

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

Description :

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)

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.
