The remote Redhat Enterprise Linux 5 / 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2779 advisory.

    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.

    The following packages have been upgraded to a newer upstream version: nss (3.21.3), nss-util (3.21.3).

    Security Fix(es):

    * Multiple buffer handling flaws were found in the way NSS handled cryptographic data from the network. A     remote attacker could use these flaws to crash an application using NSS or, possibly, execute arbitrary     code with the permission of the user running the application. (CVE-2016-2834)

    * A NULL pointer dereference flaw was found in the way NSS handled invalid Diffie-Hellman keys. A remote     client could use this flaw to crash a TLS/SSL server using NSS. (CVE-2016-5285)

    * It was found that Diffie Hellman Client key exchange handling in NSS was vulnerable to small subgroup     confinement attack. An attacker could use this flaw to recover private keys by confining the client DH key     to small subgroup of the desired group. (CVE-2016-8635)

    Red Hat would like to thank the Mozilla project for reporting CVE-2016-2834. The CVE-2016-8635 issue was     discovered by Hubert Kario (Red Hat). Upstream acknowledges Tyson Smith and Jed Davis as the original     reporter of CVE-2016-2834.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise 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.
