@TG1999 @pombredanne I have a question about Alpine migration. We are fetching one URL and processing the data without grouping by CVE.

The problem is that each URL reports a package version along with its fixed CVEs. How can we obtain a unique identifier for this importer? Is it a good idea to restructure the data and create a large mapping, using the CVE as the unique identifier?

Proposed structure:
CVE: [purl_1, purl_2, ...]

Example:
Package: aom

Sources:
https://secdb.alpinelinux.org/v3.22/main.json -> CVEs: "CVE-2021-30473", "CVE-2021-30474", "CVE-2021-30475"
https://secdb.alpinelinux.org/v3.21/main.json -> CVEs: "CVE-2021-30473", "CVE-2021-30474", "CVE-2021-30475"

@ziadhany do we have an issue for this? if not, please enter an issue.

[ziadhany]

@keshav-space Yes, I think we already have an issue for this.

see:

• Unsupported Alpine versions univers#59

@ziadhany Great, let's also open an issue here in VulnerableCode to review Alpine pipeline once aboutcode-org/univers#59 is resolved.

Okay, I have created an issue in VulnerableCode:

• Review Alpine pipeline after univers #59 fix #2127
