      network protocol.

  <description>
    <p>Multiple vulnerabilities have been discovered in the Key Distribution
      Center in MIT Kerberos 5. Please review the CVE identifiers referenced
      below for details.
    </p>
  </description>
  <impact type="normal">
    <p>A remote attacker could send a specially crafted request, possibly
      resulting in execution of arbitrary code with the privileges of the
      process or a Denial of Service condition. Additionally, a remote attacker
      could impersonate a kadmind server and send a specially crafted packet to
      the password change port, which can result in a ping-pong condition and a
      Denial of Service condition.
    </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-krb5-1.11.4"
    </code>
