Ubuntu: Add as a Vulnerability Specification Source

[gh-greg]

Ubuntu: Add as a Vulnerability Specification Source:

As Ubuntu seems to have the largest Linux market share, proposed to
directly include Canonical "OVAL/Security-Notices", as a Grype Vulnerability source.

In 2022, Ubuntu seemed to be the largest Linux Market Share:
https://www.enterpriseappstoday.com/stats/linux-statistics.html

Thus, Ubuntu based Docker containers are deployed in lots of microservices.
Once working, long term Ubuntu releases may stay in product deployment
for an extended period ... gathering discovered defects.

Today, Ubuntu issues "Security Notices" , through a service known as OVAL.

https://ubuntu.com/security/oval # oscap oval eval --report report.html oci.com.ubuntu.focal.usn.oval.xml
https://ubuntu.com/security/notices
https://ubuntu.com/security/notices/USN-5675-1

Why is this needed:

Tenable, Grype's competition, seems to be using Ubuntu's security feed, as a data source.
What are other vendors besides Tenable, doing ?
https://www.tenable.com/

(1) Example: Is Ubuntu publishing Vulns, that Mitre is not listing ?

(1.a) Ubuntu : Flags "Heimdal vulnerabilities"

https://ubuntu.com/security/notices?order=newest&release=xenial&details=Heimdal+

(1.b) Mitre CVE : By way of contrast, these Ubuntu "Heimdal vulnerabilities",
do not seem to be clearly noted , or even found, here in the CVE/Mitre Vulnerability feed:

https://cve.mitre.org/cgi-bin/cvekey.cgi?keyword=heimdal+ubuntu

Additional context:

(a) Possibly Related Issues:

• Distro matchers should be guided by package metadata not detected distro #86
• reporting the relevant CVE number when GHSA is reported #204
• next issue

(b) Is there already a Grype enhancement, to suggest using Canonical Ubuntu as a Vulnerability Source ?

https://github.com/anchore/grype/issues?page=1&q=is%3Aissue+is%3Aopen++ubuntu

---

(c) What are the existing Data Sources , of Grype Vulnerability specifications ?

Using this source file, Grype seems to use these things as Vulnerability Data Sources:

https://github.com/anchore/grype/blob/a000a69b84211b9d928aff676d0b44b9ae83f7dc/schema/cyclonedx/vulnerability.xsd

List of Common Weaknesses Enumerations (CWEs) codes that describes this vulnerability.: 
For example 399 (of https://cwe.mitre.org/data/definitions/399.html)

metric values used to score the vulnerability: see attack vector in 
https://www.first.org/cvss/v3.1/specification-document

vulnerability as defined by the risk scoring methodology: 
For example CVE-2019-15842 (of https://nvd.nist.gov/vuln/detail/CVE-2019-15842)

based on CVSS v2 standard: 
https://www.first.org/cvss/v2/guide

based on CVSS v3 standard: 
https://www.first.org/cvss/v3.1/specification-document

based on OWASP Risk Rating: 
https://www.owasp.org/index.php/OWASP_Risk_Rating_Methodology

based on Open FAIR specification:

https://nvd.nist.gov/vuln/detail/CVE-2019-15842

Hi @gh-greg -- we are already using Canonical's vulnerability feeds when matching Ubuntu packages! Is there a specific reason to use OVAL otherwise?

If you'd like to see the data source for each vulnerability, you could run something like:

grype -o json ubuntu:latest | jq '.matches[].vulnerability.dataSource'

This is what we see, which is from Canonical:

"http://people.ubuntu.com/~ubuntu-security/cve/CVE-2022-29458"
"http://people.ubuntu.com/~ubuntu-security/cve/CVE-2022-3219"
"http://people.ubuntu.com/~ubuntu-security/cve/CVE-2022-3358"
"http://people.ubuntu.com/~ubuntu-security/cve/CVE-2022-37434"

@kzantow : Let's close this. I must have gone off "half-cocked", and today cannot fully reproduce, what I was talking about when I filed this.
