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. E.
