    <p>It was discovered that Gentoo’s OpenDKIM ebuild does not properly set
      permissions or place the pid file in a safe directory.

  <impact type="normal">
    <p>A local attacker could escalate privileges.</p>
  </impact>
  <workaround>
    <p>Users should ensure the proper permissions are set as discussed in the
      referenced bugs.
    </p>
  </workaround>
  <resolution>
    <p>All OpenDKIM users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=mail-filter/opendkim-2.10.3-r8"
    </code>
