      SSRT2229 /usr/sbin/ping  (Severity - Medium)

             A potential security vulnerability has been
             reported within HP Tru64 UNIX /ur/sbin/ping,
             which could potentially result in denial
             of service (DoS). This may be in the form of
             local security domain risks.

      SSRT2275 HP Tru64 UNIX Buffer Overflows (Severity -
                                  see specific list below)

              Potential buffer overflows have been reported
              for HP Tru64 UNIX where, under certain
              circumstances,  a non-privileged user may gain
              unauthorized privileged access. This may be in
              the form of local and remote security domain

      Early Release Patches (ERPs) are now available for
      all supported versions of HP Tru64 UNIX. The ERP kits
      use dupatch to install and will not  install over any
      Customer-Specific-Patches (CSPs) which have file
      intersections with the ERPs. Contact your normal
      support channel and request HP Tru64 services elevate
      a case to  Support Engineering if a CSP must be merged
      with one of the ERPs. Please review the README file for
      each patch prior to installation.

    NOTE: These ERPs supercede ERPs delivered with the release
    of SSRT2257 HP Tru64 UNIX /usr/bin/su buffer overflow

    After completing the update, HP and Compaq strongly
    recommend that you perform an immediate backup of  the

    begin with updated software. Otherwise, the updates
    must be re-applied after a future restore operation.
    Also, if at some future time the system is upgraded to
    a later patch release or version release,  reinstall the
    appropriate ERP.
