All Docker Enterprise containers must be restricted from acquiring additional privileges.
High Severity
<VulnDiscussion>Restrict the container from acquiring additional privileges via suid or sgid bits. A process can set the no_new_priv bit in the kernel. It persists across fork, clone, and execve. The no_new_priv bit ensures that the process or its children processes do not gain any additional privileges via suid or sgid bits. This way a lot of dangerous operations become a lot less dangerous because there is no possibility of subverting privileged binaries. no_new_priv prevents LSMs like SELinux from transitioning to process labels that have access not allowed to the current process. By default, new privileges are not restricted.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
