The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6779-1 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-2024-4767, CVE-2024-4768,     CVE-2024-4769, CVE-2024-4771, CVE-2024-4772, CVE-2024-4773, CVE-2024-4774, CVE-2024-4775, CVE-2024-4776,     CVE-2024-4777, CVE-2024-4778)

    Jan-Ivar Bruaroey discovered that Firefox did not properly manage memory when audio input connected with     multiple consumers. An attacker could potentially exploit this issue to cause a denial of service, or     execute arbitrary code. (CVE-2024-4764)

    Thomas Rinsma discovered that Firefox did not properly handle type check when handling fonts in PDF.js. An     attacker could potentially exploit this issue to execute arbitrary javascript code in PDF.js.
