   Critical Information about the New and Revised HP Bulletins

CIAC has obtained information from Hewlett Packard regarding a new security
vulnerability and a revision to an existing security patch.  This bulletin
contains information which updates CIAC Bulletin F-02 (Summary of HP
Bulletins).

The patches are presented first in a table format, then a summary of the
vulnerability information is presented for each patch.  

CIAC has also created a document, available on our FTP server ciac.llnl.gov as
/pub/ciac/bulletin/f-fy95/hppatchs.txt.  This document contains the entire
list of all HP Bulletins and patches, and is an update to CIAC Bulletin F-02.

HP has set up an automatic server to allow patches and other security 
information to be retrieved over the Internet.  To utilize this server, send a 
message to support@support.mayfield.hp.com.  The subject line of the message 
will be ignored. The body (text) of the message should contain the words

send XXXX

where XXXX is the identifier for the information you want retrieved.  For 
example, to retrieve the patch PHSS_4834, the message would be "send 
PHSS_4834".

Other information that can be retrieved include the HP SupportLine mail 
service user's guide (send guide.txt), the readme file for a patch (send doc 
PHSS_4834), and the original HP bulletin (send doc HPSBUX9410-018).

HP also has a World Wide Web server to browse and retrieve bulletins and 
patches.  To utilize this server, use a WWW client and connect to 
http://support.mayfield.hp.com.

IMPORTANT NOTE:  Hewlett Packard updates patches periodically.  These updates 
are not reflected in the text of each HP bulletin.  The overview presented 
here contains current information on the patches available at the time of the 
release of this CIAC bulletin.  If you request an updated patch, when you try 
to retrieve the patch you will receive a message stating that the patch is 
obsolete and the name of the patch which supersedes it.

Hewlett Packard has made sum and MD5 checksums available for their patches
and for their security bulletins.  See the detailed explanation for
HPSBUX9408-016 in CIAC bulletin F-02 for information on how to access and
utilize these checksums.

Previous CIAC Bulletins and other information are available via anonymous FTP 
from ciac.llnl.gov (IP address 128.115.19.53).

CIAC has several self-subscribing mailing lists for electronic publications:
1.  CIAC-BULLETIN for Advisories, highest priority - time critical 
    information, and Bulletins, important computer security information;
2.  CIAC-NOTES for Notes, a collection of computer security articles;
3.  SPI-ANNOUNCE for official news about Security Profile Inspector (SPI)
    software updates, new features, distribution and availability;
4.  SPI-NOTES, for discussion of problems and solutions regarding the use of
    SPI products.

CIAC's mailing lists are managed by a public domain software package called 
ListProcessor, which ignores E-mail header subject lines. To subscribe (add 
yourself) to one of our mailing lists, send the following request as the
E-mail message body, substituting CIAC-BULLETIN, CIAC-NOTES, SPI-ANNOUNCE or 
SPI-NOTES for "list-name" and valid information for "LastName" "FirstName" 
and "PhoneNumber" when sending

E-mail to ciac-listproc@llnl.gov:
          subscribe list-name LastName, FirstName PhoneNumber
    e.g., subscribe ciac-notes O'Hara, Scarlett 404-555-1212 x36

You will receive an acknowledgment containing address, initial PIN, and 
information on how to change either of them, cancel your subscription, or get 
help.

receive CIAC bulletins. If you are not part of these communities, please 
contact your agency's response team to report incidents. Your agency's team 
will coordinate with CIAC. The Forum of Incident Response and Security Teams 
(FIRST) is a world-wide organization. A list of FIRST member organizations 
and their constituencies can be obtained by sending E-mail to

Appendix II: Details of each HP Bulletin


After every patch is installed, be sure to examine /tmp/update.log for any 
relevant WARNINGs or ERRORs.  This can be done by typing  "tail -60 
/tmp/update.log | more", then paging through the next three screens via the 
space bar, looking for WARNING or ERROR messages.

==================================================
HPSBUX9411-019: Support Watch, dated November 30, 1994

This vulnerability, which can allow users to increase their access
privileges, exists ONLY in HP 9000 series 800 running HP-UX revisions 8.0,
8.02, 8.06 and 9.0.  Later HP-UX releases including 9.04 are NOT affected by
this vulnerability.

Obtain patch PHSS_4874, install it per the installation instructions included 
with the patch.

==================================================
HPSBUX9409-017: CORE-DIAG vulnerability, dated September 21, 1994 (Revised 
October 18, 1994, then revised December 1, 1994)

This vulnerability can allow a user to increase their access privileges.  The 
vulnerability exists for all HP-UX systems using the CORE-DIAG fileset.  No 
patches will be available for versions of HP_UX prior to version 8.0.

The patch to install depends on which operating system version and series you
are currently using.  To determine the operating system version of your 
system, display the file /system/UX-CORE/index with the "more" or "pg" 
command. The line will look similar to:

          fv:  A.BX.YY.ZZ

Where X is the major revision, YY is the minor revision, and ZZ is the PCO
index. For example, if your system needed to install an item on the chart
below, (HP-UX 9.00.4A) the major revision would be "9", the minor revision
would be "00" and the PCO index would be "4A".  Note that these patches are
quite large. Use the following chart to determine which patch to retrieve and
install in /tmp:

Operating System             Series        Apply patch

HP-UX 8.0, 8.06               800          PHSS_4578
HP-UX 8.02                    800          PHSS_4577
HP-UX 8.05, 8.07              700          PHSS_4574
HP-UX 9.00.2O or 9.00.3A      800          PHSS_4532
HP-UX 9.00.4A                 800          PHSS_4660
HP-UX 9.01                    700          PHSS_4475
HP-UX 9.03, 9.05              700          PHSS_4863
HP-UX 9.04                    800          PHSS_4913

Obtain necessary patches, install per the installation instructions included 
with the patches.
