Hewlett Packard will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Bulletin as soon as possible. - - ------------------------------------------------------------------------- PROBLEM: Novell Netware 3.12 release B.10.08 or earlier, and B.09.05 or earlier allows unauthorized users to read files. PLATFORM: HP 9000 Series 700/800s running only specific releases of HP-UX 9.X and 10.X. See below. DAMAGE: Allows users unauthorized file read access. SOLUTION: Apply the following patches as needed: PHNE_11684 for HP-UX release 9.04, or PHNE_11341 for HP-UX release 10.01, and PHNE_11722 for HP-UX release 10.01, or PHNE_11723 for HP-UX release 10.10, or PHNE_11724 for HP-UX release 10.20. AVAILABILITY: All patches are available now. - - ------------------------------------------------------------------------- I. A. Background Hewlett-Packard Company has discovered a defect in the Novell Netware 3.12 product running on HP-UX. This defect is seen on both 9.04 and 10.X operating systems, and allows users to read files from an unauthorized PC. Native Netware is exempt from this defect. NOTE: The product in question only runs on HP-UX releases 9.04, 10.01, 10.10, or 10.20. B. Fixing the problem For HP-UX 9.04 users, simply obtain Netware release B.09.08.002 to be used as a full product replacement. This is the patch PHNE_11684. Installation will require rebooting the server. For 10.01 users, before continuing to use Netware, first obtain PHNE_10341 (the full product replacement patch B.10.08) and then apply patch PHNE_11722 (B.10.08.002). PHNE_11722 will not install unless PHNE_10341 has been previously installed. For HP-UX 10.10 and 10.20 update to the Netware B.10.08 release from the latest application release CD, DART32 or newer. Then install the appropriate patch (see above). C. Recommended solution The patch is a cumulative patch and and fully fixes the discovered vulnerability. D.
