Prose
The Docker Enterprise hosts user namespace must not be shared.
High Severity
<VulnDiscussion>Do not share the host's user namespaces with the containers. User namespaces ensure that a root process inside the container will be mapped to a non-root process outside the container. Sharing the user namespaces of the host with the container thus does not isolate users on the host with users on the containers. By default, the host user namespace is shared with the containers until user namespace support is enabled.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
