The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:0079 advisory.

    The Berkeley Internet Name Domain (BIND) is an implementation of the Domain     Name System (DNS) protocols. BIND includes a DNS server (named); a resolver     library (routines for applications to use when interfacing with DNS); and     tools for verifying that the DNS server is operating correctly.

    A flaw was found in the way BIND handled requests for TKEY DNS resource     records. A remote attacker could use this flaw to make named (functioning     as an authoritative DNS server or a DNS resolver) exit unexpectedly with an     assertion failure via a specially crafted DNS request packet.
    (CVE-2015-5477)

    A denial of service flaw was found in the way BIND parsed certain malformed     DNSSEC keys. A remote attacker could use this flaw to send a specially     crafted DNS query (for example, a query requiring a response from a zone     containing a deliberately malformed key) that would cause named functioning     as a validating resolver to crash. (CVE-2015-5722)

    A denial of service flaw was found in the way BIND processed certain     records with malformed class attributes. A remote attacker could use this     flaw to send a query to request a cached record with a malformed class     attribute that would cause named functioning as an authoritative or     recursive server to crash. (CVE-2015-8000)

    Note: This issue affects authoritative servers as well as recursive     servers, however authoritative servers are at limited risk if they perform     authentication when making recursive queries to resolve addresses for     servers listed in NS RRSETs.

    Red Hat would like to thank ISC for reporting the CVE-2015-5477,     CVE-2015-5722, and CVE-2015-8000 issues. Upstream acknowledges Jonathan     Foote as the original reporter of CVE-2015-5477, and Hanno Bck as the     original reporter of CVE-2015-5722.

    All bind users are advised to upgrade to these updated packages, which     contain backported patches to correct these issues. After installing the     update, the BIND daemon (named) will be restarted automatically.

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.
