The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6649-1 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-2024-1547, CVE-2024-1548,     CVE-2024-1549, CVE-2024-1550, CVE-2024-1553, CVE-2024-1554, CVE-2024-1555, CVE-2024-1557)

    (CVE-2024-1551)

    Gary Kwong discovered that Firefox incorrectly generated codes on 32-bit ARM devices, which could lead to     unexpected numeric conversions or undefined behaviour. An attacker could possibly use this issue to cause     a denial of service. (CVE-2024-1552)

    Ronald Crane discovered that Firefox did not properly manage memory when accessing the built-in profiler.
