NOTICE: There are no restrictions for distribution of this
Bulletin provided that it remains complete and intact.

The information in the following Security Bulletin should be
acted upon as soon as possible.  Hewlett-Packard Company 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:  ipcs(1) has a potential buffer overflow.

IMPACT:   Potential for local users to get unauthorized access,
          create denial of service (DoS).

PLATFORM: HP9000 Series 700/800 running HP-UX release B.11.00
          only.

SOLUTION: Download and install patch PHCO_29043

MANUAL ACTIONS: No

AVAILABILITY: The patch is available now from itrc.hp.com

CHANGE SUMMARY:  Rev. 01  Added general release patch info.
 -----------------------------------------------------------------
**REVISED 01 **
 A. Background
    A potential buffer overflow in ipcs(1) has been identified
    and now has been fixed.  This problem only affects HP-UX
    release B.11.00.

    NOTE: This problem does not impact HP NonStop Servers,
          HP OpenVMS, nor Tru64 UNIX/Trucluster servers.

    The SSRT thanks Davide Del Vecchio for reporting this
    potential vulnerability to HP.

**REVISED 01 **
- -->> AFFECTED VERSIONS
- -->>    The following is a list by HP-UX revision of
- -->>   affected filesets and the fileset revision or
- -->>   patch containing the fix.  To determine if a
- -->>   system has an affected version, search the
- -->>   output of "swlist -a revision -l fileset"
- -->>   for an affected fileset, then determine if
- -->>   a fixed revision or the applicable patch is
- -->>   installed.

- -->>   HP-UX B.11.00
- -->>   =============
- -->>   OS-Core.UX-CORE,fr=B.11.00,fa=HP-UX_B.11.00_32/64,v=HP
- -->>   OS-Core.CORE-SHLIBS,fr=B.11.00,fa=HP-UX_B.11.00_32/64,v=HP
- -->>   fix: install PHCO_29043

- -->>  END AFFECTED VERSIONS


**REVISED 01**
 B. Recommended solution
- -->>HP has prepared a patch that can be installed to fully
- -->>   rectify the problem.  If the temporary depot was downloaded
- -->>   it MUST be removed before this general release patch is
- -->>   installed.

- -->>   NOTE: Failure to properly remove this could cause
- -->>   corruption of the system and inadvertently reintroduce the
- -->>   problem at a later time when the temporary patch is finally
- -->>   removed.

- -->>   Verification  that the temporary depot is installed,
- -->>   in /usr/lib/libcrash can be done by executing:
- -->>     $what libcrash*
- -->>    libcrash.2:
- -->>        UNOF_29043 : libcrash $Revision: 1.5 $ SHARED
- -->>    libcrash.a:
- -->>        UNOF_29043 : libcrash $Revision: 1.5 $ ARCHIVE
- -->>    libcrash.sl:
- -->>        UNOF_29043 : libcrash $Revision: 1.5 $ SHARED

- -->>    Remove the temporary  depot using Software Distributor
- -->>    (SD), then apply PHCO_29043 for release HP-UX B.11.00.

    bulletin has been implemented on HP-UX 11.XX systems providing
    that the fix is completely implemented in a patch with no
    manual actions required.  The Security Patch Check tool cannot
    verify fixes implemented via a product upgrade.
