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. ----------------------------------------------------------------------- To subscribe to automatically receive NEW future HP Security Bulletins from the HP SupportLine mail service via electronic mail, send the following in the TEXT PORTION OF THE MESSAGE to support@support.mayfield.hp.com (no Subject is required): subscribe security_info To retrieve the index of all HP Security Bulletins, send the following: send security_info_list To obtain a copy of the HP SupportLine mail service user's guide, send the following: send guide.txt For security concerns, write to: security-alert@hp.com -----------------------------------------------------------------------
