1. Problem Description
        
        After installation of the product, the file /var/adm/isl/ifile
        is left readable by all users. This file contains, among other
        things, the encrypted root password, and the encrypted owner
        password.


2. Vulnerable Supported Versions

        Operating System        Version         Affected Files
        ------------------------------------------------------------------
        UnixWare 7              All             /var/adm/isl/ifile
        Open UNIX               8.0.0           /var/adm/isl/ifile


3. Solution

        Caldera recommends that all affected systems change the file
        modes of /var/adm/isl/ifile to be readable only by root:

        # chmod 400 /var/adm/isl/ifile

        In addition, Caldera also recommends that you change the root
        and owner passwords.
