Description: Security Vulnerability in HP GlancePlus
===============================================================================

-----------------------------------------------------------------------
HEWLETT-PACKARD SECURITY BULLETIN: #00011, 04 May 94
-----------------------------------------------------------------------

_______________________________________________________________________
PROBLEM: Security vulnerability in product executables for HP GlancePlus
product revision B.09.00 and all earlier revisions, on all
releases of HP-UX.
PLATFORM: HP 9000 series 300/400s and 700/800s.
DAMAGE: A vulnerability exists in the GlancePlus product which allows
non-root users who can execute glance or gpm to gain root
privileges.
SOLUTION: Obtain and apply fix as outlined below. For HP-UX 9.X a new
version of Glance is available in the April 1994 Application
release which addresses the problem. All customers on support
should already have access to the fixed release.
AVAILABILITY: The fix is currently available.
_______________________________________________________________________

I. Glance Update

A. Problem

A vulnerability exists in the /usr/perf/bin programs Glance and gpm
revisions prior to and including B.09.00 (for series 700/800 systems),
and in the /usr/perf/bin/glance program revision prior to and including
A.09.06 (for series 300/400 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.

B. Fixing the problem

The problem can be eliminated by installing the latest release of the
product, which contains a version of glance and gpm revision B.09.01
or greater (for series 700/800 systems) or glance revision A.09.07 or
greater (for series 300/400 systems). The GlancePlus version can be
determined on 9.X systems using the command "what /usr/perf/bin/glance".

PLATFORM OS GLANCE ver. Action
-------- -------- ----------- ---------------
300/400 HPUX 8.X all No patch currently available
HPUX 9.X A.09.06 or earlier Update to GlancePlus A.09.07
HPUX 9.X A.09.07 None
700/800 HPUX 8.X all No patch currently available
HPUX 9.X A.X or B.09.00 Update to GlancePlus B.09.01
HPUX 9.X B.09.01 None

There is currently no fix available for glance on HP-UX 8.X. Users on
8.X releases are advised to use the workaround below.

The GlancePlus product for HP-UX 9.X has been released on the HP-UX
Application Software Release CD for April 1994. All customers with
software support for HP GlancePlus should 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.

Hewlett-Packard recommends that all GlancePlus customers concerned
with the security of their HP-UX systems update from the April release
media 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
chmod 744 /usr/perf/bin/gpm

NOTE: The gpm program file will only exist on your system if you
have installed revision B.09.00, or later of the GlancePlus
product.

NOTE: On 8.X systems, the glance executable is /usr/bin/rxux/glance.
