PROBLEM:  Security vulnerability in the BIND executable

PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.XX & 11.XX.

DAMAGE:   May allow remote users to gain root access or to disrupt
          normal operation on the name server.

SOLUTION: Install patches (below) which upgrade BIND to version 4.9.7,
          or upgrade to version 8.1.2.

AVAILABILITY: All patches are available now.
- -------------------------------------------------------------------------
   A. Background
      The CERT advisory (CA-99-14) detailed several BIND vulnerabilities.
      The Berkeley Internet Name Domain (BIND) is an implementation of
      the Domain Name System (DNS) protocols. Complete details can be
      found at:

   B. Recommended solution
      Apply the appropriate patches for BIND components noted below.

  s700_800 HP-UX release 10.01, 10.10 & 10.20  BIND 4.9.7    PHNE_20618
  s700_800 HP-UX release 10.24 (VVOS)          BIND 4.9.7    PHNE_21288
  s700_800 HP-UX release 11.00                 BIND 4.9.7    PHNE_20619
  s700_800 HP-UX release 11.04 (VVOS)          BIND 4.9.7    PHNE_21090

      The bind revision 8.1.2 upgrade is available for HP-UX 11.00 via
      a web page:

      Registration for the download is necessary, once done, there is
      a link for installation instructions underneath the download

      You have the an option of staying with bind 4.X or moving to
      bind 8.X.  The security holes mentioned in CERT advisory CA-99-14
      have been fixed in both versions.  Bind 8.X provides many
      additional features. This is the latest version featuring full
      support for negative caching (RFC2308) the clarifications in
      RFC 2181, DNS security extensions in RFC 2065, multiple virtual
      name servers, split DNS via "forward" zones, and general
      enhancements.  Please reference the web page above for full

      NOTE: There are some migration issues that need to be addressed,
