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-4546-1 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, conduct cross-     site scripting (XSS) attacks, spoof the site displayed in the download dialog, or execute arbitrary code.

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

The remote Oracle Linux 6 host has a package installed that is affected by multiple vulnerabilities as referenced in the ELSA-2020-4158 advisory.

  - Mozilla developers reported memory safety bugs present in Firefox 80 and Firefox ESR 78.2. Some of these     bugs showed evidence of memory corruption and we presume that with enough effort some of these could have     been exploited to run arbitrary code. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and     Firefox ESR < 78.3. (CVE-2020-15673)

  - Firefox sometimes ran the onload handler for SVG elements that the DOM sanitizer decided to remove,     resulting in JavaScript being executed after pasting attacker-controlled data into a contenteditable     element. This vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3.
    (CVE-2020-15676)

  - By exploiting an Open Redirect vulnerability on a website, an attacker could have spoofed the site     displayed in the download file dialog to show the original site (the one suffering from the open redirect)     rather than the site the file was actually downloaded from. This vulnerability affects Firefox < 81,     Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15677)

  - When recursing through graphical layers while scrolling, an iterator may have become invalid, resulting in     a potential use-after-free. This occurs because the function     APZCTreeManager::ComputeClippedCompositionBounds did not follow iterator invalidation rules. This     vulnerability affects Firefox < 81, Thunderbird < 78.3, and Firefox ESR < 78.3. (CVE-2020-15678)

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