Synopsis

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

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3876-1 advisory.

 Chad Seaman discovered that Avahi incorrectly handled certain messages. An attacker could possibly use this issue to cause a denial of service. (CVE-2017-6519, CVE-2018-1000845)

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

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