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-3874-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked in to opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, gain additional     privileges by escaping the sandbox, or execute arbitrary code. (CVE-2018-18500, CVE-2018-18501,     CVE-2018-18502, CVE-2018-18503, CVE-2018-18504, CVE-2018-18505)

    It was discovered that Firefox allowed PAC files to specify that requests to localhost are sent through     the proxy to another server. If proxy auto-detection is enabled, an attacker could potentially exploit     this to conduct attacks on local services and tools. (CVE-2018-18506)

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.
