"The remote Ubuntu 14.04 LTS / 16.04 LTS / 20.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-7348-1 advisory.

    It was discovered that the Python ipaddress module contained incorrect information about which IP address
    ranges were considered private or globally reachable. This could possibly result in
    applications applying incorrect security policies. This issue only affected Ubuntu 14.04 LTS and Ubuntu
    16.04 LTS. (CVE-2024-4032)

    It was discovered that Python incorrectly handled quoting path names when using the venv module. A local
    attacker able to control virtual environments could possibly use this issue to execute arbitrary code when
    the virtual environment is activated. (CVE-2024-9287)

    It was discovered that Python incorrectly handled parsing bracketed hosts. A remote attacker could
    possibly use this issue to perform a Server-Side Request Forgery (SSRF) attack. This issue only affected
    Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2024-11168)

    It was discovered that Python incorrectly handled parsing domain names that included square brackets. A
    remote attacker could possibly use this issue to perform a Server-Side Request Forgery (SSRF) attack.
    (CVE-2025-0938)

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
