The remote Ubuntu 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7191-1 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-2025-0237, CVE-2025-0239,     CVE-2025-0240, CVE-2025-0242, CVE-2025-0243, CVE-2025-0247)

    Irvan Kurniawan discovered that Firefox incorrectly handled memory when breaking lines in text, leading to     a use-after-free vulnerability. An attacker could possibly use this issue to cause a denial of service or     possibly execute arbitrary code. (CVE-2025-0238)

    Nils Bars discovered that Firefox incorrectly handled memory when using JavaScript Text Segmentation. An     attacker could possibly use this issue to cause a denial of service. (CVE-2025-0241)

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.
