    <p>RunC is a CLI tool for spawning and running containers according to the
      OCI specification.
    </p>
  </background>
  <description>
    <p>A vulnerability was discovered in runC that allows additional container
      processes via ‘runc exec’ to be ptraced by the pid 1 of the
      container.  This allows the main processes of the container, if running
      as root, to gain access to file-descriptors of these new processes.
    </p>
  </description>
  <impact type="normal">
    <p>An attacker, who is able to successfully escape the container or modify
      runC’s state before process initialization, could escalate privileges.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All runC users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-emulation/runc-1.0.0_rc2-r2"
    </code>
