Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

An update for nss, nspr, nss-softokn, and nss-util is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

Network Security Services (NSS) is a set of libraries designed to support the cross-platform development of security-enabled client and server applications. The nss-util packages provide utilities for use with the Network Security Services (NSS) libraries. Netscape Portable Runtime (NSPR) provides platform independence for non-GUI operating system facilities.

The following packages have been upgraded to a newer upstream version:
nss (3.21.0), nss-util (3.21.0), nspr (4.11.0). (BZ#1310581, BZ#1303021, BZ# 1299872)

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)

Red Hat would like to thank the Mozilla project for reporting these issues. Upstream acknowledges Eric Rescorla as the original reporter of CVE-2016-1978; and Tim Taubert as the original reporter of CVE-2016-1979.

Bug Fix(es) :

* The nss-softokn package has been updated to be compatible with NSS 3.21. (BZ#1326221)

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

Mozilla NSPR was updated to version 4.12, fixing following bugs :

Added a PR_GetEnvSecure function, which attempts to detect if the program is being executed with elevated privileges, and returns NULL if detected. It is recommended to use this function in general purpose library code.

Fixed a memory allocation bug related to the PR_*printf functions

Exported API PR_DuplicateEnvironment, which had already been added in NSPR 4.10.9

Several minor correctness and compatibility fixes.

Mozilla NSS was updated to fix security issues :

MFSA 2016-15/CVE-2016-1978: Use-after-free in NSS during SSL connections in low memory

MFSA 2016-35/CVE-2016-1950: Buffer overflow during ASN.1 decoding in NSS

MFSA 2016-36/CVE-2016-1979: Use-after-free during processing of DER encoded keys in NSS.
