Overview

github.com/openshift/builder/pkg/build/builder is a package for image run by build pods to execute image building+pushing.

Affected versions of this package are vulnerable to Insecure Permissions. The build container runs with high privileges using a chrooted environment instead of runc. If an attacker can gain access to this build container, they can potentially utilize the raw devices of the underlying node, such as the network and storage devices, to at least escalate their privileges to that of the cluster admin.
