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.
