The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6404-1 advisory.

    Multiple security issues were discovered in Firefox. If a user were tricked into opening a specially     crafted website, an attacker could potentially exploit these to cause a denial of service, obtain     sensitive information across domains, or execute arbitrary code. (CVE-2023-5169, CVE-2023-5170,     CVE-2023-5171, CVE-2023-5172, CVE-2023-5175, CVE-2023-5176)

    Ronald Crane discovered that Firefox did not properly manage memory when non-HTTPS Alternate Services     (network.http.altsvc.oe) is enabled. An attacker could potentially exploit this issue to cause a denial of     service. (CVE-2023-5173)

    Clment Lecigne discovered that Firefox did not properly manage memory when handling VP8 media stream. An     attacker-controlled VP8 media stream could lead to a heap buffer overflow in the content process,     resulting in a denial of service, or possibly execute arbitrary code. (CVE-2023-5217)

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.
