These versions of subnetconfig exist on HP-UX versions 9.0 and 9.01. They do not exist in prior versions of HP-UX or in versions subsequent to the above (9.03, etc.). BACKGROUND: The vulnerability is a result of an access permissions problem, and can be eliminated by applying a patch developed by HP. This problem affects HP 9000 Series 300, 400, 700, and 800 running HP-UX 9.0/9.01. IMPACT: An existing user can gain root access to the system. RECOMMENDED SOLUTION: Apply patch PHNE_3563 (series 300/400, HP-UX 9.0), or PHNE_3564 (series 700/800, HP-UX 9.0/9.01 ONLY). The patch can be obtained through HP SupportLine Mail Service or local HP Response Centers. A. HP SupportLine Mail Service To obtain the patch, send the following in the TEXT PORTION OF THE MESSAGE to support@support.mayfield.hp.com (no Subject is required): send patch_name for example: send PHNE_35nn It will automatically be emailed back to you. Note that users with an established SupportLine handle & password may also download the patch from HP SupportLine via ftp, kermit, or uucp. Detailed instructions for obtaining a SupportLine handle & password can be found in ASSIST 94-14. B. HP Response Center Support If you need additional assistance and have a support contract, you can contact your local Response Center for further help. To apply the patch to your system: a. Become superuser (or root). b. Put the patch into /tmp. c. At the shell prompt, type "sh /tmp/PHNE_35nn" d. At the shell prompt, for 9.x systems type "/etc/update -s /tmp/PHNE_35nn.updt \*" Note: "nn" refers to the last two digits of the appropriate patch from the list in step 1. Examine /tmp/update.log for any relevant WARNINGs or ERRORs. This can be done as follows: a. At the shell prompt, type "tail -60 /tmp/update.log | more" b. Page through the next three screens via the space bar, looking for WARNING or ERROR messages. Consequences of installing this patch As a result of applying this patch and closing the security hole, /etc/subnetconfig will no longer be executable by non-root users. This is consistent with the intended use of this program; it is intended for system administrators.
