CHANGE SUMMARY: New patches for CMW/BLS releases are included.
_______________________________________________________________________
I. Update
A. It has been found that all HP-UX systems have this vulnerability.
B. Fixing the problem
The vulnerability can be eliminated from releases 8.X and 9.X of
HP-UX by applying a patch.
All customers concerned with the security of their HP-UX systems
should apply the appropriate patch described above as soon as
possible.
C. How to Install the Patch (for HP-UX 8.X and 9.X)
1. Determine which patch is appropriate for your hardware platform and
operating system:
PHCO_5203 (series 700 , HP-UX 8.X), or
PHCO_5204 (series 800 , HP-UX 8.X), or
PHCO_5199 (series 300/400, HP-UX 8.X), or
PHCO_5178 (series 700 , HP-UX 9.X), or
PHCO_5193 (series 800 , HP-UX 9.X), or
PHCO_5206 (series 300/400, HP-UX 9.0), or
PHCO_5206 (series 300/400, HP-UX 9.03),or
**REVISED01** | PHCO_5442 and PHCO_5414 (series 800, HP-UX 9.08), or
| PHCO_5416 and PHCO_5295 (series 700, HP-UX 9.09), or
| PHCO_5415 and PHCO_5295 (series 700, HP-UX 9.09+).
2. Apply the patch to your HP-UX system.
Examine /tmp/update.log for any relevant WARNINGs or ERRORs. This
can be done as follows:
a. At the shell prompt, type "tail -60 /tmp/update.log | more"
b. Page through the next three screens via the space bar, looking
for WARNING or ERROR messages.
3. Impact of the patch and workaround
The patch for HP-UX releases 8.X and 9.X provides a new version of
/etc/cron and /usr/bin/at which fixes the vulnerability.

Title: Security Vulnerabilities in VirtualVault code
-------------------------------------------------------------------------
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.
____________________________________________________________________
Hewlett-Packard recommends that 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.
____________________________________________________________________
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.
