Scientific Linux Security Update : nss, nss-util, and nspr on SL6.x i386/x86_64

This script is Copyright (C) 2016 Tenable Network Security, Inc.


Synopsis :

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

Description :

The following packages have been upgraded to a newer upstream version:
nss 3.21.0, nss-util 3.21.0, nspr 4.11.0.

Security Fix(es) :

- A use-after-free flaw was found in the way NSS handled
DHE (Diffie- Hellman key exchange) and ECDHE (Elliptic
Curve Diffie-Hellman key exchange) handshake messages. A
remote attacker could send a specially crafted handshake
message that, when parsed by an application linked
against NSS, would cause that application to crash or,
under certain special conditions, execute arbitrary code
using the permissions of the user running the
application. (CVE-2016-1978)

- A use-after-free flaw was found in the way NSS processed
certain DER (Distinguished Encoding Rules) encoded
cryptographic keys. An attacker could use this flaw to
create a specially crafted DER encoded certificate
which, when parsed by an application compiled against
the NSS library, could cause that application to crash,
or execute arbitrary code using the permissions of the
user running the application. (CVE-2016-1979)
