type Version ¶

type Version struct {
	Original string
	Major    int
	Minor    int
}

Version allows extracting the "major" and "minor" versions so that we don't compare container tags from different minor versions.

This is a workaround for another problem where not all minor releases of containers have a unique CPE.

For example, take "ocs4/rook-ceph-rhel8-operator": it shipped at least 2 minor releases into the same container repository. Both those major versions use the same CPE: "cpe:/a:redhat:openshift_container_storage:4". Here are 2 example tags which fixed CVE-2020-8565:

• 4.7-140.49a6fcf.release_4.7
• 4.8-167.9a9db5f.release_4.8

This type also handles container tags which have a 'v' prefix (e.g. "openshift4/ose-metering-hive").

• v4.6.0-202112140546.p0.g8b9da97.assembly.stream
• v4.7.0-202112140553.p0.g091bb99.assembly.stream
