The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7056-1 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-2024-9392, CVE-2024-9396,     CVE-2024-9397, CVE-2024-9398, CVE-2024-9399, CVE-2024-9400, CVE-2024-9401, CVE-2024-9402, CVE-2024-9403)

    Masato Kinugawa discovered that Firefox did not properly validate javascript under the resource://pdf.js     origin. An attacker could potentially exploit this issue to execute arbitrary javascript code and access     cross-origin PDF content. (CVE-2024-9393)

    Masato Kinugawa discovered that Firefox did not properly validate javascript under the     resource://devtools origin. An attacker could potentially exploit this issue to execute arbitrary     javascript code and access cross-origin JSON content. (CVE-2024-9394)
