GitHub runs the libraries through its Dependency Graph announced last year, to match the libraries to the CVEs.
When a vulnerable library is identified, the system raises an alert to a project’s admin in their dependency graphs and repository home pages.
GitHub announced the first run of the security checker turned up “over four million vulnerabilities in over 500,000 repositories”.
On that first pass, GitHub’s post said, 450,000 of the vulns were resolved by December 1, 2017. In the months since then, “our rate of vulnerabilities resolved in the first seven days of detection has been about 30 per cent. Additionally, 15 per cent of alerts are dismissed within seven days”.
More active projects get patched quicker, but that’s not quantified in the post. GitHub’s post noted that the seven-day fix metric was met by “for almost all repositories with recent contributions”.
