    HEWLETT-PACKARD SECURITY BULLETIN: HPSBVV9706-063, 12 June 1997
-------------------------------------------------------------------------

 The information in the following Security Bulletin should be acted upon
 as soon as possible.  Hewlett Packard will not be liable for any
 consequences to any customer resulting from customer's failure to fully
 implement instructions in this Security Bulletin as soon as possible.

-------------------------------------------------------------------------

PROBLEM:  Vulnerabilities exist in syslogd, and also in servers that
          listen on well-known TCP or UDP ports.

PLATFORM: HP9000 Series 700/800s running:
             HP-UX 10.09.01 with VirtualVault A.01.00,
             HP-UX 10.16 with VirtualVault A.01.01,
             HP-UX 10.24 (VVOS) with VirtualVault A.02.00

DAMAGE:   The syslogd vulnerability could result in a potential denial
          of service or console spoofing.
          The server vulnerabilities could allow programs to access
          services on the VirtualVault system that are not designed to
          be accessible from the external network (Internet).

SOLUTION: Apply the appropriate patches to correct the vulnerability:

          HP-UX 10.09.01 with VirtualVault A.01.00:
                     PHCO_10387 and PHSS_10786
          HP-UX 10.16 with VirtualVault A.01.01:
                     PHCO_10387 and PHSS_10786
          HP-UX 10.24 (VVOS) with VirtualVault A.02.00:
                     PHNE_11096 (Series 700) and PHSS_10613
                     PHNE_11097 (Series 800) and PHSS_10613

AVAILABILITY: All patches are are available now.

I. Nature of the vulnerabilities

  A.  Syslogd
      The syslogd program can be used by a process to forward syslog
      messages that can result in a denial of service or a spoofing
      problem on the system console.

  B.  Servers
      There are well-known ports that the xdm, dtlogin and X servers
      listen on.  External programs can connect to these ports and
      could gain unauthorized access to services  using potential bugs
      in these servers.

      NOTE: At this time there are no such known vulnerabilities in
      these servers.

  C.  Fixing the problems

      Both of these problems can both be eliminated by applying the
      recommended patches.

      The problem of connecting to servers through well-know ports can
      be eliminated by disabling the well-known ports by applying the
      recommended patches.  The problem may also be eliminated from the
      external network (Internet) by installing a filtering router
      between the VirtualVault system and the external network.

  D.  Recommended solution

      Hewlett-Packard recommends that the following patches be applied
      as appropriate:

            HP-UX 10.09.01 with VirtualVault A.01.00:
                  PHCO_10387 and PHSS_10786
            HP-UX 10.16 with VirtualVault A.01.01:
                  PHCO_10387 and PHSS_10786
            HP-UX 10.24 (VVOS) with VirtualVault A.02.00:
                  PHNE_11096 (Series 700) and PHSS_10613
                  PHNE_11097 (Series 800) and PHSS_10613

       NOTE: These problems only apply to systems running the
             VirtualVault Transaction Server.
