Reverting Back to use RHSA Data
NOTE: This section is only for very specific situations where you absolutely must revert the matching system to use the RHSA data. This should not be done lightly. The newer CVE-based data is more accurate, specific, and provides a more consistent experience with other distros.
If your processing of anchore output relies on RHSA keys as vulnerability matches, or you have large RHSA-based whitelists that cannot be converted to CVE-based, then it is possible, though not recommended, to migrate your system back to using the RHSA-based feeds (centos:* groups).
Here is the process. It requires the Anchore CLI with access to the API as well as direct access to the internal policy engine API endpoint. That may require a docker exec or kubectl exec call
to achieve and will be deployment/environment specific.
-
Revert the distro mapping records that map centos, fedora, and rhel to use the RHEL vuln data.
- With API access to the policy engine directly (output omitted for brevity), remove the existing distro mappings to RHEL data. These are the used by Anchore:
curl -X DELETE -u admin:foobar http://localhost:8087/v1/distro_mappings?from_distro=centos curl -X DELETE -u admin:foobar http://localhost:8087/v1/distro_mappings?from_distro=rhel curl -X DELETE -u admin:foobar http://localhost:8087/v1/distro_mappings?from_distro=fedora- Continuing with API access to the policy engine directly, replace the removed mappings with new mappings to the centos feeds:
curl -H "Content-Type: application/json" -X POST -u admin:foobar -d'{"from_distro":"centos", "to_distro":"centos", "flavor":"RHEL"}' http://localhost:8087/v1/distro_mappings curl -H "Content-Type: application/json" -X POST -u admin:foobar -d'{"from_distro":"fedora", "to_distro":"centos", "flavor":"RHEL"}' http://localhost:8087/v1/distro_mappings curl -H "Content-Type: application/json" -X POST -u admin:foobar -d'{"from_distro":"rhel", "to_distro":"centos", "flavor":"RHEL"}' http://localhost:8087/v1/distro_mappingsNote: if something went wrong and you want to undo the progress you’ve made, just make the same set of calls as the last two steps in the same order but with the
to_distrovalues set to ‘rhel’.- Now, ensure you are back where you have access to the main Anchore API and the Anchore CLI installed. Disable the existing rhel feed groups
anchore-cli system feeds config vulnerabilities --disable --group rhel:5 anchore-cli system feeds config vulnerabilities --disable --group rhel:6 anchore-cli system feeds config vulnerabilities --disable --group rhel:7 anchore-cli system feeds config vulnerabilities --disable --group rhel:8anchore-cli system feeds delete vulnerabilities --group rhel:8 anchore-cli system feeds delete vulnerabilities --group rhel:7 anchore-cli system feeds delete vulnerabilities --group rhel:6 anchore-cli system feeds delete vulnerabilities --group rhel:5- Enable the centos feed groups that have the RHSA vulnerability data

anchore-cli system feeds list) then you’ll need to delete the centos data groups as well to ensure a clean re-syncin the next steps. This is accomplished with:anchore-cli system feeds delete vulnerabilities --group centos:5 anchore-cli system feeds delete vulnerabilities --group centos:6 anchore-cli system feeds delete vulnerabilities --group centos:7 anchore-cli system feeds delete vulnerabilities --group centos:8- Now do a sync to re-match any images using rhel/centos to the RHSA data

Note in the last command output that the OS vulnerabilities are again showing ‘RHSA’ matches. The restoration to RHSA-based vuln data is complete.
