Description: Security vulnerability in executables for HP GlancePlus
===============================================================================
- -----------------------------------------------------------------------
HEWLETT-PACKARD SECURITY BULLETIN: #00044, 07 January 97
- -----------------------------------------------------------------------
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.
Permission is granted for copying and circulating this bulletin to
Hewlett-Packard (HP) customers (or the Internet community) for the
purpose of alerting them to problems, if and only if, the bulletin is
not edited or changed in any way, is attributed to HP, and provided such

_______________________________________________________________________
PROBLEM: Security vulnerability in executables for HP GlancePlus
PLATFORM: HP 9000 series 700 and 800s.
DAMAGE: A vulnerability exists in the GlancePlus product which allows
non-root users to gain root privileges.
SOLUTION: Apply patch PHSS_8231 for HP-UX 9.X on series 700
PHSS_8232 for HP-UX 9.X on series 800
PHSS_8233 for HP-UX 10.01 on series 700/800
PHSS_9116 for HP-UX 10.10 * see note below
PHSS_9524 for HP-UX 10.10 ** see note below
PHSS_9117 for HP-UX 10.20
AVAILABILITY: All patches are available now.
_______________________________________________________________________
I. Glance Update
A. Problem
A vulnerability exists in the /usr/perf/bin or /opt/perf/bin
programs Glance (for both series 700 and 800 systems). The
vulnerability allows non-root users to gain access to files
regardless of ownership and permissions. This could be exploited
to gain root-level access. The GlancePlus Motif (GPM) product
version is NOT affected by this security fault, and therefore is
not a part of the patch.
B. Fixing the problem
The problem can be eliminated by installing the latest release of
the product, which contains a fix for this vulnerability along
with new enhancements.
The product version can be determined on 9.X systems using the
command "what /usr/perf/bin/glance" .
The product version can be determined on 10.X systems using the
command "what /opt/perf/bin/glance" .
The following table will help guide patch selection.
PLATFORM OS release product version Action required
-------- ---------- --------------- ---------------
s700 HPUX 9.X any Apply patch PHSS_8231
s800 HPUX 9.X any Apply patch PHSS_8232
s700/800 HPUX 10.01 any Apply patch PHSS_8233
s700/800 HPUX 10.10 B.10.13 only Apply patch PHSS_9116
s700/800 HPUX 10.10 B.10.10 to B.10.12 Apply patch PHSS_9524
s700/800 HPUX 10.20 any Apply patch PHSS_9117
NOTE: The * above indicates that this patch is applicable if the
Glance product version is B.10.13.
Similarly, ** applies if the Glance product version is B.10.10,
B.10.11 or B.10.12.
For HP-UX 9.X, a new version of Glance is available in the
November 1996 Application Release which addresses the problem.
All customers on support should already have access to this fixed
release.
The GlancePlus product for HP-UX 10.10 and 10.20 will be
re-released on the HP-UX Application Software Release CD for
January 1997. The HP-UX 10.01 version of these fixes will only be
available as a patch (number above).
All customers with software support for GlancePlus will have access
to the latest GlancePlus release media containing the fix. If for
some reason you do not have access to the latest media, contact
your HP Response Center representative.
Hewlett-Packard recommends that all GlancePlus customers concerned
with the security of their HP-UX systems obtain and apply the
patches above as soon as possible.
As a workaround until the update can be applied, you may execute the
following commands as the root user in order to restrict access to
the product to only the root user:
chmod 744 /usr/perf/bin/glance
C. Impact of the patch
The patches provide a new version of the necessary executables
to fix the vulnerability. Installation instructions are contained
within the patches.
D. Impact
These patches for HP-UX releases 9.X and 10.X provide not only
code to avoid this vulnerability but also enhancements to the
functionality previously unavailable.
