Vulnerability in JRE (revised01) 16 February 2001 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Java Runtime Environment Vendor: Sun Microsystems Operating System: HP-UX 10.20 HP-UX 10.24 HP-UX 11.00 HP-UX 11.04 HP-UX 11.11 Platform: HP9000 Series 700/800 Impact: Increased Privileges Access Required: Remote Ref: ESB-2000.381 - --------------------------BEGIN INCLUDED TEXT-------------------- Document ID: HPSBUX0011-132 Date Loaded: 20010214 Title: Sec. Vulnerability in JRE (revised01) - ---------------------------------------------------------------------- *REVISED01* HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0132, 30 NOV '00 Last Revised: 14 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 an untrusted class to call into a disallowed class under certain circumstances. PLATFORM: *REVISED01* --->>> This security bulletin applies to Java on HP9000 Series --->>> 700/800 running HP-UX releases 10.20, 10.24, 11.00, 11.04, --->>> and 11.11 only. 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. CHANGE SUMMARY: Added VVOS releases 10.24 and 11.04. Updated JDK and JRE releases available. - ----------------------------------------------------------------------- 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). *REVISED01* C. Recommended solution - --->>>JDK and JRE 1.1.8.04 or higher for HP-UX 10.20, 10.24, 11.00, 11.04 and 11.11. - --->>>JDK and JRE 1.2.2.04 * or higher for HP-UX 11.00, 11.04 and 11.11. - --->>>JDK and JRE 1.3.0.00 for HP-UX 11.XX * NOTE: Version 1.2.2.04 is the minimum to resolve the issue addressed in this security bulletin. - --->>> However, JDK and JRE version 1.2.2.07 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. - ----------------------------------------------------------------------- D.
