There is no fixed version for Centos:8 buildah.
NVD Description
Note: Versions mentioned in the description apply only to the upstream buildah package and not the buildah package as distributed by Centos.
See How to fix? for Centos:8 relevant fixed versions and status.
Go before 1.17 does not properly consider extraneous zero characters at the beginning of an IP address octet, which (in some situations) allows attackers to bypass access control that is based on IP addresses, because of unexpected octal interpretation. This affects net.ParseIP and net.ParseCIDR.
