Scientific Linux Security Update : nss on SL5.x i386/x86_64
Medium Nessus Plugin ID 85623
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionIt 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.
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.
SolutionUpdate the affected packages.
