     a fixed revision or the applicable patch is
     installed.

 B. Recommended solution

    Note:
          The issue can be avoided by upgrading to
          Bind 9.2.0 which is available now.  The security
          bulletin HPSBUX0208-209 has details about required
          revisions of Bind 9.2.0 for B.11.00 and B.11.11.

     HP-UX B.11.00 Bind 8.1.2
     ========================
     BIND812 for B.11.00 has been discontinued.  It will
     become obsolete by the end of March, 2004.  A new
     version of BIND812 for B.11.00 has been created to
     address the issue of this bulletin.  However, it is
     recommended that customers upgrade to Bind 9.2.0 now.
     More details can be found here:

        <http://software.hp.com/portal/swdepot/
         displayProductInfo.do?productNumber=BIND812>

     The new version of BIND812 for B.11.00 is available from
     the ftp site listed below.  Since BIND812 for B.11.00 has
     been discontinued, this version will not be available
     from software.hp.com.

     HP-UX B.11.11 Bind 8.1.2
     ========================

     Until a patch is available a temporary depot has been created
     to install a version of /usr/sbin/named which addresses the
     issue.  The depot is available from the ftp site listed
     below.  The depot will not install the new named file unless
     PHNE_28450 has been installed first.  PHNE_28450 is available
     from <http://itrc.hp.com>.

    =========================================================

    For B.11.00 download BIND812v005.depot from the
    following ftp site.

    For B.11.11 download SSRT3653UX.depot from the
    following ftp site.
