Vulnerability in JRE The documents are listed below. ------------------------------------------------------------------------------- Document ID: HPSBUX0102-141 Date Loaded: 20010221 Title: Sec. Vulnerability in JRE ---------------------------------------------------------------------------- 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: /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 -------------------------------------------------------------------------- D.
