The remote Ubuntu 16.04 ESM host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5747-1 advisory.
ISC BIND 9.x before 9.9.9-P2, 9.10.x before 9.10.4-P2, and 9.11.x before 9.11.0b2, when lwresd or the named lwres option is enabled, allows remote attackers to cause a denial of service (daemon crash) via a long request that uses the lightweight resolver protocol. (CVE-2016-2775)
ISC BIND through 9.9.9-P1, 9.10.x through 9.10.4-P1, and 9.11.x through 9.11.0b1 allows primary DNS servers to cause a denial of service (secondary DNS server crash) via a large AXFR response, and possibly allows IXFR servers to cause a denial of service (IXFR client crash) via a large IXFR response and allows remote authenticated users to cause a denial of service (primary DNS server crash) via a large UPDATE message. (CVE-2016-6170)
Note that Nessus has not tested for these issues but has instead relied only on the application’s self-reported version number.
