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.
