  <impact type="normal">
    <p>A context-dependent attacker can load kernel modules without privileges
      by nullifying enforced module
      prefixes. Execution of arbitrary files or a Denial of Service can be
      caused through the included vulnerable LZO library.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All BusyBox users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-apps/busybox-1.23.1"
    </code>
