The remote Ubuntu 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6010-1 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-2023-29537, CVE-2023-29540,     CVE-2023-29543, CVE-2023-29544, CVE-2023-29547, CVE-2023-29548, CVE-2023-29549, CVE-2023-29550,     CVE-2023-29551)

    Irvan Kurniawan discovered that Firefox did not properly manage fullscreen notifications using a     combination of window.open, fullscreen requests, window.name assignments, and setInterval calls. An     attacker could potentially exploit this issue to perform spoofing attacks. (CVE-2023-29533)

    Lukas Bernhard discovered that Firefox did not properly manage memory when doing Garbage Collector     compaction. An attacker could potentially exploits this issue to cause a denial of service.
    (CVE-2023-29535)
