Issue Description:

To improve the accuracy and relevance of vulnerability information for Ubuntu systems, we need to integrate the official Ubuntu CVE list. This will ensure that our vulnerability data for Ubuntu systems is up-to-date and comprehensive.

Tasks:

• Review Ubuntu CVE API: Examine the Ubuntu CVE list API documentation to understand the available endpoints and data format.
• Integrate API: Develop functionality to fetch and process CVE data from the Ubuntu CVE API.
• Ensure data consistency: Implement checks to ensure that the Ubuntu CVE data is consistently integrated with our existing vulnerability data sources.
• Test integration: Create and run tests to verify that the Ubuntu CVE data is correctly fetched, processed, and integrated.

Additional Notes:

• Direct API: https://ubuntu.com/security/cves.json
• Ensure that any rate limits or access restrictions of the Ubuntu API are respected.
• Review and update related documentation to include details on the integration with the Ubuntu CVE list.
