SUMMARY: Security vulnerabilities in HP-UX Remote Watch can be used to increase access privileges of users. BACKGROUND: The vulnerability in Remote Watch is contained in the WATCH-RUN fileset for releases of HP-UX. IMPACT: This vulnerability can allow users to increase their access privileges which may result in system compromise. All HP 300/400 and 700/800 series machines running HP-UX 8.x or 9.x which have Remote Watch installed are affected. RECOMMENDED SOLUTION: Obtain and install the appropriate patch. HP has an automatic server to allow patches and other security information to be retrieved over the Internet. To utilize this server, send an e-mail message to support@support.mayfield.hp.com. The subject line of the message is ignored and the body (text) of the message should contain the words send XXXX where XXXX is the identifier for the information you want retrieved. For example, to retrieve the patch PHSS_4834, the message would be "send PHSS_4834". Other information that can be retrieved include the HP SupportLine mail service user's guide (send guide.txt), the readme file for a patch and the original HP bulletin (send doc HPSBUX9501-020). HP also has a World Wide Web server to browse and retrieve bulletins and patches. To utilize this server, use a WWW client and connect to http://support.mayfield.hp.com. IMPORTANT NOTE: Hewlett Packard updates patches periodically. These updates are not reflected in the text of each HP bulletin. The overview presented here contains current information on the patches available at the time of the release of this CIAC bulletin. If you request an updated patch, when you try to retrieve the patch you will receive a message stating that the patch is obsolete and the name of the patch which supersedes it. Hewlett Packard has made sum and MD5 checksums available for their patches and for their security bulletins. See the detailed explanation for HPSBUX9408-016 in ASSIST 94-37 for information on how to access and utilize these checksums. The patch to install to correct the Remote Watch problem depends on which operating system version and machine series you are currently using. Use the following table to determine which patch to retrieve and install: Operating System Series Apply patch HP-UX 8.x 800 PHSS_5185 HP-UX 9.x 800 PHSS_5136 HP-UX 8.x 700 PHSS_5180 HP-UX 9.x 700 PHSS_5107 HP-UX 8.x 300/400 PHSS_5168 HP-UX 9.x 300/400 PHSS_5120 Obtain necessary patches, and install per the installation instructions included with the patches. After the patch is installed, be sure to examine /tmp/update.log for any relevant WARNINGs or ERRORs. This can be done by typing "tail -60 /tmp/update.log | more", then paging through the screens via the space bar, looking for WARNING or ERROR messages.
