  <background>
    <p>MIT Kerberos 5 is a suite of applications that implement the Kerberos
      network protocol.
    </p>
  </background>
  <description>
    <p>Multiple vulnerabilities have been discovered in MIT Kerberos 5. Please
      review the CVE identifiers referenced below for details.
    </p>
  </description>
  <impact type="high">
    <p>A remote attacker may be able to execute arbitrary code with the
      privileges of the administration daemon or the Key Distribution Center
      (KDC) daemon, cause a Denial of Service condition, or possibly obtain
      sensitive information. Furthermore, a remote attacker may be able to
      spoof Kerberos authorization, modify KDC responses, forge user data
      messages, forge tokens, forge signatures, impersonate a client, modify
      user-visible prompt text, or have other unspecified impact. 
    </p>
  </impact>
  <workaround>
    <p>There is no known workaround at this time.</p>
  </workaround>
  <resolution>
    <p>All MIT Kerberos 5 users should upgrade to the latest version:</p>
    
    <code>
      # emerge --sync
      # emerge --ask --oneshot --verbose "&gt;=app-crypt/mit-krb5-1.9.2-r1"
    </code>
