"The remote Ubuntu 16.04 LTS / 18.04 LTS / 20.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-8199-1 advisory.

    Martin Kaesberger discovered that OpenStack Glance's image processing could return the contents of
    arbitrary files. An attacker could possibly use this issue to exfiltrate sensitive data. This issue only
    affected Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. (CVE-2024-32498)

    Hyeongeun Ji and Abhishek Kekane discovered several server-side request forgery vulnerabilities in
    OpenStack Glance's image import. An attacker could possibly use this issue to bypass URL validation checks
    and redirect to internal services. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS.
