      Title:  Sec. Vulnerability with Ignite on Trusted systems

-------------------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #00111, 17 Feb 2000
-------------------------------------------------------------------------

The information in the following Security Advisory should be acted upon
as soon as possible.  Hewlett-Packard Company 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:  Trusted systems may have vulnerabilities if a password
          field in /etc/passwd is blank.

PLATFORM: HP-9000 Series700/800 running release HP-UX 11.X only.

DAMAGE:   Increase of privileges.

SOLUTION: Verify that all entries in /etc/passwd have "*" in the
          password field if the system is trusted.

-------------------------------------------------------------------------
I.
   A. Background
      Each password field in /etc/passwd should be "*" in a trusted
      system.  This is normally handled automatically.  One way for
      the password field to be set to a blank is to create a system
      image of a trusted system with Ignite-UX and not save /etc/passwd.
      By default Ignite-UX omits /etc/passwd.

   B. Fixing the problem
      In a trusted system if the system or the /etc/passwd file has
      been restored, verify that the password fields in /etc/passwd
      are "*".  If Ignite-UX is used to create an image of a trusted
      system, _override_the_default_ so that /etc/passwd is saved in
      the image.  See man(1M) make_sys_image and note the -f file option.
