The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-5257-1 advisory.

  - When ldns version 1.7.1 verifies a zone file, the ldns_rr_new_frm_str_internal function has a heap out of     bounds read vulnerability. An attacker can leak information on the heap by constructing a zone file     payload. (CVE-2020-19860)

  - When a zone file in ldns 1.7.1 is parsed, the function ldns_nsec3_salt_data is too trusted for the length     value obtained from the zone file. When the memcpy is copied, the 0xfe - ldns_rdf_size(salt_rdf) byte data     can be copied, causing heap overflow information leakage. (CVE-2020-19861)

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