The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6703-1 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-2024-2609, CVE-2024-2611,     CVE-2024-2614, CVE-2024-2615)

    Hubert Kario discovered that Firefox had a timing side-channel when

    performing RSA decryption. A remote attacker could possibly use this

    issue to recover sensitive information. (CVE-2023-5388)

    It was discovered that Firefox did not properly handle WASM register values in some circumstances. An     attacker could potentially exploit this issue to cause a denial of service. (CVE-2024-2606)

    Gary Kwong discovered that Firefox incorrectly updated return registers for JIT code on Armv7-A systems.
    An attacker could potentially exploit

    this issue to execute arbitrary code. (CVE-2024-2607)

    Ronald Crane discovered that Firefox did not properly manage memory during character encoding. An attacker     could potentially exploit this issue to

    cause a denial of service. (CVE-2024-2608)

    Georg Felber and Marco Squarcina discovered that Firefox incorrectly

    handled html and body tags. An attacker who was able to inject markup into

    a page otherwise protected by a Content Security Policy may have been able

    obtain sensitive information. (CVE-2024-2610)

    Ronald Crane discovered a use-after-free in Firefox when handling code in SafeRefPtr. An attacker could     potentially exploit this issue to cause a

    denial of service, or execute arbitrary code. (CVE-2024-2612)

    Max Inden discovered that Firefox incorrectly handled QUIC ACK frame

    decoding. A attacker could potentially exploit this issue to cause a

    denial of service. (CVE-2024-2613)

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.
