PROBLEM:        Security vulnerabilities in HP-UX Support Watch and 
                CORE-DIAG fileset.
PLATFORM:       HP 9000 series 700 and 800, for versions see below.
DAMAGE:         Users can increase access privileges.
SOLUTION:       Apply appropriate security patches.
_____________________________________________________________________________
VULNERABILITY   These vulnerabilities are widely known and used to compromise
ASSESSMENT:     systems.  CIAC urges affected sites to install the
                appropriate patches immediately.

   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. 

The patches are presented first in a table format (Appendix 1), then a 
summary of the vulnerability information is presented for each patch 
(Appendix 2).  

CIAC has also created a document which contains the entire list of all 
HP Bulletins and patches, INCLUDING the ones mentioned here. This 
document is separately distributed as CERT-NL document S-95-03 :
Summary of security related HP patches.

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stating that the patch is obsolete and the name of the patch which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. 

CIAC wishes to thank Hewlett Packard for the information contained in this
bulletin.

Appendix 2: 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_5037
HP-UX 9.04                    800          PHSS_4913

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