HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0141, 21 Feb. '01
----------------------------------------------------------------------------
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 execute unauthorized
commands under certain circumstances.
PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.20, 10.24, 11.00,
11.04, and 11.11 only. This security bulletin applies to Java
on HP-UX, and does not cover software shipped on Linux, nor on
Windows/NT.
POSSIBLE RESULT: Improper permission may be granted in some cases.
SOLUTION: Install the latest Java releases as described below.
AVAILABILITY: The fixed releases are available immediately.
----------------------------------------------------------------------------
I.
A. Background
A vulnerability in certain versions of the Java(TM) Runtime Environment
may allow malicious Java code to execute unauthorized commands. Since
no permission is granted by default, the circumstances necessary to
exploit this vulnerability are relatively rare. On the Java
Development Kit 1.1.x (JDKTM 1.1.x) (browsers included), an applet must
be signed to have execute permission (signed applets may execute
anything in JDK 1.1.x.).
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 listed in
section C. below.
For JDK/JRE 1.1, 1.2.2 and 1.3 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 1.1.8.05 or higher for HP-UX 10.20, 10.24 and 11.XX.
JDK and JRE 1.2.2.07 or higher for HP-UX 11.XX.
JDK and JRE 1.3.0.00 or higher for HP-UX 11.XX.
-------------------------------------------------------------------------
1.) HP-UX: Determining Java version information for JDK, JRE
-------------------------------------------------------------------------
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.
-------------------------------------------------------------------------
2.) HP-UX: Determining Java version information for JPI
-------------------------------------------------------------------------
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.)
b.) 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
