          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.
