Title: Sec. Vulnerability in JRE
----------------------------------------------------------------------
HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0132, 30 NOV '00
----------------------------------------------------------------------
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 an untrusted class
to call into a disallowed class under certain
circumstances.
PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.20 and
11.00 only. This security bulletin applies to Java
on HP-UX. It does not cover software shipped on Linux
nor on Windows/NT.
POSSIBLE RESULT: Improper access rights may be granted in some cases.
SOLUTION: Install the latest Java releases as described below,
and/or check your system for Java Plug-ins as outlined
below.
AVAILABILITY: The fixed releases are available immediately.
-----------------------------------------------------------------------
I.
A. Background
Java 1.1 and 1.2 applications may permit unauthorized access
in some cases.
B. Fixing the problem
Obtain and install the latest releases of the Java products.
For JDK/JRE 1.1 and JDK/JRE 1.2.2 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.
Section C. 2.) below guides you in checking your system
for Java Plug-ins for Windows (OBAM product).
C. Recommended solution
JDK and JRE 1.1.8.04 or higher for HP-UX 10.20 and 11.x.
JDK and JRE 1.2.2.04* or higher for HP-UX 11.x
JDK and JRE 1.3 (when available) for HP-UX 11.x.
* NOTE: Version 1.2.2.04 is the minimum to resolve the issue
addressed in this security bulletin.
However, JDK and JRE version 1.2.2.06 or later are
preferred since they incorporate product quality
enhancements.
----------------------------------------------------------------------
1.) HP-UX: Determining Java version information for JDK, JRE, and 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
or is any alternate location where the JDK or JRE may have been
installed.
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
----------------------------------------------------------------------
2.) Determining Java Runtime Environment (JRE) version information
for HP-UX 10.20 and 11.00, and Java Plug-in for Microsoft
Windows which is shipped as part of the ServiceControl Manager
product (HP-UX 10.20 and 11.00)
----------------------------------------------------------------------
The Java Runtime Environment for HP-UX and the Java Plug-in for
Microsoft Windows are delivered as part of the ServiceControl Manager
product. The versions of Java Runtime Environment and Java Plug-in
which shipped with the ServiceControl Manager product in Application
Release 49 (6/00) and Application Release 50 (9/00) are subject to
this vulnerability; the versions of ServiceControl Manager beginning with
Application release 51 (12/00) and HP-UX release 11.i have repaired
versions of the Java Runtime Environment and Java Plug-in and are NOT
subject to this vulnerability.
PART ONE
To determine if your HP-UX 10.20 or 11.00 system is vulnerable,
perform the following command on the HP-UX system:
swlist -l product OBAM ServControlMgr
If the swlist output contains any of the lines listed below, your
HP-UX system is subject to this vulnerability. If the swlist output
does not contain any of the lines below, skip to PART TWO to determine
if you have a related vulnerability.
OBAM B.11.00.05.0.17 Object Action Manager user
interface framework for HP-UX tools
OBAM B.11.00.05.1.04 Object Action Manager user
interface framework for HP-UX tools
ServControlMgr A.01.00 HP-UX ServiceControl Manager
ServControlMgr A.01.01 HP-UX ServiceControl Manager
ServControlMgr A.01.01.01 HP-UX ServiceControl Manager
If your HP-UX system is subject to this vulnerability, retrieve the
most recent version (A.02.02 or later) of ServiceControl Manager
bundle B8337BA from the HP web site:
http://www.hp.com/go/servicecontrol
Follow the link to ServiceControl Manager B8337BA bundle, then follow
the instructions to install version A.02.02 or later of that bundle.
PART TWO
If you have installed the Java Plug-in for Microsoft Windows on a PC
according to the instructions provided with ServiceControl Manager,
that PC may be vulnerable. To determine if a PC is subject to this
vulnerability, open a DOS window and execute the command "jre -help".
Among other things, the Java version is displayed. If the version
string displayed is "1.1.8" , the PC is subject to this vulnerability.
If the version string is "1.1.8_005", the PC is not subject to this
vulnerability.
Any other version string is not compatible with the OBAM versions
identified above, and indicates that you installed the Java Plug-in
from a source other than the OBAM versions mentioned above. Check
with that source to determine whether your Java Plug-in is subject to
this vulnerability.
On each PC that has installed the Java Plug-in for Microsoft Windows
from a vulnerable HP-UX system, do one of the following:
a. Remove the Java Plug-in by opening Control Panel - Add/Remove
Programs, selecting "Java Plug-in 1.1.3" and choosing "Add/Remove".
Note that removing the Java Plug-in will disallow accessing
ServiceControl Manager from this PC.
-or-
b. Update the Java Plug-in by installing the fixed version, which
you downloaded in PART ONE above. You can find instructions on how to
perform this installation at the following URL (substitute the
hostname of your Central Management Server where indicated):
http://yourhost:1188/mx/
Follow the "Configure Browser" link and re-install the Java Plug-in
on your PC.
