 -------------------------------------------------------------------
    HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0174,
    Originally issued:  22 October 2001
 -------------------------------------------------------------------

The information in the following Security Bulletin 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 Bulletin as
soon as possible.

 -------------------------------------------------------------------
ISSUE:   Sun Microsystems discovered a potential security issue
         in the Java Runtime Environment.  The issue poses a
         possible security risk by allowing malicious Java code
         to access the system clipboard under certain circumstances.

PLATFORM:  HP9000 Series 700/800 running HP-UX releases 10.20 and
           11.x only.  This security bulletin applies to Java
           on HP-UX.  It does not cover software shipped on Linux
           or Windows/NT.

POSSIBLE RESULT: Contents of system clipboard is accessed improperly.

MANUAL ACTIONS: Determine what Java version you have, see below.

SOLUTION:  Install the latest Java releases, as described below.

AVAILABILITY: These fixed releases are on www.hp.com/go/java now.
              They are not available from itrc.hp.com
 --------------------------------------------------------------------
   A. Background

   A vulnerability in certain versions of the Java(TM) Runtime
   Environment may allow malicious Java code to access the system
   clipboard under certain circumstances.

   There are no known attacks reported based on this vulnerability
   to the best of Sun's knowledge.

   B. Fixing the problem

     Obtain and install the latest releases of the Java products.
     For JDK/JRE 1.2.2 and JDK/JRE 1.3.x based releases go to
              www.hp.com/go/java.
     Section C. 1.) below will guide you in determining your
     installed Java version on HP-UX.

   C. Recommended solution

         JDK and JRE 1.2.2.10 or higher for HP-UX 11.x.
         JDK and JRE 1.3.0.02 or higher for HP-UX 11.x.
         JDK and JRE 1.3.1.01 or higher for HP-UX 11.x.

 --------------------------------------------------------------------
 1.) HP-UX: Determining Java version information for JDK, JRE, & JPI
 --------------------------------------------------------------------
There are two mechanisms to determine which versions of the Java
JDK/SDK (developer kit), JRE (runtime), or JPI (Java Plugin for
Netscape) you have installed.

First, you can use the following command to list the bundle revisions
for any installed Java products:

      /usr/sbin/swlist -l bundle | grep -i java

Second, you can ask Java to identify itself by executing the
following:

      <path>/bin/java -version

where path is typically

      /opt/java - for Java 1.1
      /opt/java1.2 - for Java 1.2
      /opt/java1.3 - for Java 1.3

but may be an alternate location as specified during setup.

The plugin (JPI) is installed in user's home directories, so
you will need to check its version using the following.

For Java 1.2:

      $HOME/.netscape/java/bin/java -version

For Java 1.1, you must use:

      what $HOME/.netscape/java/bin/PA_RISC/green_threads/jre

NOTE: Do not rely on Netscape's Help/About_Plug-ins menu to find
the version number of the Plugin, because in some cases the
version number is incorrect.

    a.) Unplugging the Plugin (Since the Plugin is manually
        installed into Netscape, it must be manually removed
        as well.)

    If you have a plugin that you wish to remove because it has a
    security issue, in addition to doing a swremove of the product
    you must also do the following for Java 1.1 and Java 1.2:

    rm -f $HOME/.netscape/plugins/javaplugin.sl
    rm -rf $HOME/.netscape/java
