The remote Ubuntu host is missing one or more security updates.


The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS / 20.10 host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4691-1 advisory.

- Buffer overflow in the lldp_decode function in daemon/protocols/lldp.c in lldpd before 0.8.0 allows remote attackers to cause a denial of service (daemon crash) and possibly execute arbitrary code via vectors involving large management addresses and TLV boundaries. (CVE-2015-8011)

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