    <p>
    The MIT Kerberos 5 administration library libkadm5srv contains a
    heap overflow in the code handling password changing.
    </p>
  </description>
  <impact type="high">
    <p>
    Under specific circumstances an attacker could execute arbitary
    code with the permissions of the user running mit-krb5, which could be
    the root user.
    </p>
  </impact>
  <workaround>
    <p>
    There is no known workaround at this time.
    </p>
  </workaround>
  <resolution>
    <p>
    All mit-krb5 users should upgrade to the latest version:
    </p>
    <code>
    # emerge --sync
    # emerge --ask --oneshot --verbose &quot;&gt;=app-crypt/mit-krb5-1.3.6&quot;</code>
  </resolution>
