COMMAND
sendmail
SYSTEMS AFFECTED
HP 9000 Series 700/800s running versions of HP-UX 9.X thru 10.10
PROBLEM
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. This allows unauthorized
access. Note that HP-UX release 10.20 is not affected by this
issue. The source for this text is Hp advisory.
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. 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.
