The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-4474-1 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, trick the user     in to installing a malicious extension, spoof the URL bar, leak sensitive information between origins, or     execute arbitrary code. (CVE-2020-15664, CVE-2020-15665, CVE-2020-15666, CVE-2020-15670)

    It was discovered that NSS incorrectly handled certain signatures. An attacker could possibly use this     issue to expose sensitive information. (CVE-2020-12400, CVE-2020-12401, CVE-2020-6829)

    A data race was discovered when importing certificate information in to the trust store. An attacker could     potentially exploit this to cause an unspecified impact. (CVE-2020-15668)

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