 HEWLETT-PACKARD COMPANY SECURITY ADVISORY: HPSBUX0207-203
 Originally issued: 29 July 2002
 -----------------------------------------------------------------

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: The HP ChaiVM EZloader does not verify JAR signatures
         for new services.

PLATFORM: Apppliances and networked printers such as, but not
           limited to: HP 4100, HP 45nn, HP 8150 printers.

DAMAGE: Potential unauthorized access, denial of service.

SOLUTION: Operate behind a firewall. Set the EWS (Embedded
           Web Server) password.

MANUAL ACTIONS: Set the EWS password.
 ----------------------------------------------------------------
 A. Background

    HP ChaiVM is a small Java(tm) virtual machine for use in
    embedded systems. At one time HP provided an EZloader
    utility for installing applications (Chailets). EZloader
    does not verify JAR signatures. This allows any Chailet to
    be installed.

    HP ChaiVM is designed to be operated from behind a firewall
    where systems within the firewall are trusted.

    Java is a U.S. trademark of Sun Microsystems, Inc.

 B. Fixing the problem

    The recommended countermeasure for customers who wish to
    keep unauthorized users from loading Chailets is to set the
    EWS (embedded webserver) password.

    Operate behind a firewall where systems within the firewall
    are trusted.
