  <background>
    <p>sudo (su “do”) allows a system administrator to delegate authority
      to give certain users (or groups of users) the ability to run some (or
      all) commands as root or another user while providing an audit trail of
      the commands and their arguments.
    </p>

  <description>
    <p>The fix present in app-admin/sudo-1.8.20_p1 (GLSA 201705-15) was
      incomplete as it did not address the problem of a command with a newline
      in the name.
    </p>
  </description>
  <impact type="high">
    <p>A local attacker could execute arbitrary code with root privileges.</p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All sudo users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-admin/sudo-1.8.20_p2"
    </code>
