Hewlett Packard will not be liable for any consequences to any customer resulting from customer's failure to fully implement instructions in this Security Advisory as soon as possible. ------------------------------------------------------------------------- PROBLEM: Recent sendmail patches for HP-UX releases 9.X thru 10.10 PLATFORM: HP 9000 Series 700/800s running versions of HP-UX 9.X thru 10.10 DAMAGE: Allows unauthorized access. SOLUTION: Cleanse the password file as noted below on any machines which have ever had the following sendmail patches installed: PHNE_9621 on all platforms with HP-UX releases 9.X, PHNE_9622 on all platforms with HP-UX releases 10.00, 10.01, and 10.10, PHNE_10033 on all platforms with HP-UX releases 9.X, NOTE HP-UX release 10.20 is not affected AVAILABILITY: N/A ------------------------------------------------------------------------- I. A. Background Since December 1996 three specific sendmail patches (PHNE_9621, PHNE_10033, and PHNE_9622) have been released by Hewlett-Packard Company. If installed, they incorrectly added new user and group entries in the password and group files. NOTE: HP-UX release 10.20 is not affected by this issue. B. Recommended solution The system administrator needs to perform the following commands on the command line only. Do not use SAM to fix this issue at this time. grep '^sm[0-9]*' /etc/passwd The suspect entries have a ",.." in the password field. That ",.." entry needs to be replaced with a "*". The change can be easily done with vipw (1M). Simply removing the patch will not remove these erroneous entries from the password file. The action above needs to be taken whether or not the patch is removed. C.
