  <background>
    <p>PolicyKit is a toolkit for controlling privileges for system-wide
      services.
    </p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been found in PolicyKit:</p>
    
    <ul>
      <li>Error messages in the pkexec utility disclose the existence of local
        files (CVE-2010-0750).
      </li>
      <li>The pkexec utility initially checks the effective user ID of its
        parent process for authorization, instead of checking the real user ID
        (CVE-2011-1485).
      </li>
      <li>Members of the "wheel" group are able to execute commands as an
        administrator without a password (CVE-2011-4945).
      </li>
    </ul>
  </description>
  <impact type="high">
    <p>A local attacker could gain elevated privileges or sensitive
      information.
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All PolicyKit users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=sys-auth/polkit-0.104-r1"
    </code>
