The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-6738-1 advisory.

    Fabian Bumer, Marcus Brinkmann, and Jrg Schwenk discovered that LXD incorrectly handled the handshake     phase and the use of sequence numbers in SSH Binary Packet Protocol (BPP). If a user or an automated     system were tricked into opening a specially crafted input file, a remote attacker could possibly use this     issue to bypass integrity checks.

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

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