-----BEGIN PGP SIGNED MESSAGE-----Hash: SHA1SECURITY BULLETINTITLE: (SSRT0822) Java(tm) Runtime Environment - Proxy and JVM Potential Security VulnerabilitiesNOTICE: There are no restrictions for distribution of this Bulletinprovided that it remains complete and intact.Posted at:http://www.support.compaq.com/patches/mailing-list.shtmlRELEASE DATE: May 2002SEVERITY: HIGHSOURCE: Compaq Computer Corporation Compaq Services Software Security Response TeamREFERENCE: SUN Bulletin #00216 & #00218, CVE CAN-2002-0058 , CVE CAN-2002-0076________________PROBLEM SUMMARY: When using Microsoft Internet Explorer or NetScape Navigator to browse to Compaq products incorporating affected versions of the Java Runtime Environment, users may become vulnerable to attack from untrusted applets. These applets may be able to increase their privileges on the user system and potentially gain un- authorized access to system resources. This potential problem would exist on either side of a corporate firewall. Sun Microsystems published two security bulletins regarding potential vulnerabilities in Java(tm). o The first is a security bulletin (#00216) regarding a potential runtime environmental redirection issue that may allow an untrusted applet to monitor requests to and responses from an HTTP proxy server when a persistent connection is used between a client and an HTTP proxy server. NOTE: Only systems that have a HTTP proxy configured would be vulnerable to this potential exploit. o The second is a security bulletin (#00218) regarding a potential vulnerability to attack of the Java Runtime Environment Bytecode Verifier. The security advisory states, "A vulnerability in the Java(TM) Runtime Environment Bytecode Verifier may be exploited by an untrusted applet to escalate privileges."__________________VERSIONS IMPACTED: Compaq Management Software Compaq Insight Manager 7, Compaq Insight Manager XE, the Compaq Management Agents and the Remote Insight Lights-Out Edition Card leverage Java technology to deliver portions of their functionality. The Java software causing this problem is delivered as part of the Java Runtime Environment used to enable access to these management products and as part of the server-side software embedded in Compaq Insight Manager XE and Compaq Insight Manager 7. o Compaq Insight Manager XE Compaq Insight Manager XE uses the Microsoft Java Runtime Environment integrated into Microsoft Internet Explorer.=3D3D20 o Compaq Insight Manager 7 Compaq Insight Manager 7 uses the Sun Java Runtime Environment version 1.3.1 in place of the Microsoft Java Runtime Environment. o Compaq Management Agents See resolution Section o Remote Insight Lights-Out Edition See resolution Section Compaq Tru64 UNIX V4.0f SDK and JRE 1.1.7B-2 V4.0g SDK and JRE 1.1.7B-2 V5.0a SDK and JRE 1.1.7B-6 V5.1 SDK and JRE 1.1.8-6 (default) and 1.2.2-6 Compaq Nonstop Himalaya No applets run on the Compaq NonStop Himalaya operating systems. This is not a vulnerability on these systems. Compaq OpenVMS V7.2 V7.2-1 SDK and JRE 1.1.6-2 V7.2-1h1 SDK and JRE 1.1.6-2 V7.2-1h2 SDK and JRE 1.1.6-2 V7.2-2 SDK and JRE 1.1.6-2 V7.3 SDK and JRE 1.1.8-5 (includes fix) *Please note that this is an issue for the Alpha architecture only. OpenVMS on Vax does not support Java.___________RESOLUTION: The following table outlines the suggested resolutions to the vulnerabilities described above. Suggested remedies will be different on a product-by-product depending on developer of the Java Runtime Environment and any dependencies for synchronization between server and client side components. Compaq Insight Manager XE Compaq Insight Manager XE uses the Microsoft Java Runtime Environment integrated into Microsoft Internet Explorer. Compaq recommends that Compaq Insight Manager XE users upgrade to Compaq Insight Manager 7 SP1 that will be available for download in the first half of May athttp://www.compaq.com/manage. Compaq Insight Manager 7 SP1 leverages version 1.3.1_02 of the Sun Java Runtime Environment that addresses the vulnerability described above. Prior to the release of Compaq Insight Manager 7 SP1, Compaq recommends that users exercise care when browsing to sites outside of the internal network using a browser with a vulnerable version of the Microsoft Java Runtime Environment. While it is possible to update the browser to the version of the Java Runtime Environment recommended by Microsoft, this version has not been tested with Compaq Insight Manager XE and Compaq cannot guarantee that Insight Manager XE will function properly. Compaq Insight Manager 7 Compaq Insight Manager 7 uses the Sun Java Runtime Environment version 1.3.1 in place of the Microsoft Java Runtime Environment. Compaq is in the process of incorporating version 1.3.1_02 of the runtime environment, which fixes the aforementioned vulnerability, into Compaq Insight Manager 7 Service Pack 1. Compaq Insight Manager 7 SP1 will be available at the beginning of May. Users may not use version 1.3.1_02 of the plug-in with the current version of Compaq Insight Manager 7 as newer versions of the Sun Java Runtime Environment are not backwards compatible and the Insight Manager 7 may not function properly if client and server side runtime environments are not of the same version. Compaq recommends that current Compaq Insight Manager 7 users close Microsoft Internet Explorer prior to browsing to untrusted sites outside of the corporate firewall. This will ensure that the Java plug-in is closed prior to browsing to sites on the public Internet. With Compaq Insight Manager 7 SP1, the requirement to close the browser prior to visiting public sites will be removed. Compaq Management Agents Update to the version of the Java Runtime Environment that Microsoft Recommends. This information may be found athttp://www.microsoft.com/java/vm/dl_vm40.htm Remote Insight Lights-Out Edition / Integrated Lights-Out on ProLiant DL360 G2 Update to the Java(tm) 2 Runtime Environment, Standard Edition, version 1.3.1_02. To download this software simply click on the hyperlinkhttp://java.sun.com/j2se/1.3/ Compaq TRU64 UNIX Tru64 UNIX - Java 1.1.7B-10 Tru64 UNIX - Java 1.1.8-13 (includes fix) Tru64 UNIX - Java 1.2.2-12 Tru64 UNIX - Java 1.3.0-1 Tru64 UNIX - Java 1.3.1-2 (includes fix) It is critical that the information posted athttp://www.compaq.com/java/alpha be reviewed before updating Java. Tru64 UNIX 5.0 and higher include some Java-based tools that depend on the Java environment version that ships with the operating system and is installed in /usr/bin. If you change the default system Java environment version, some operating system tools, such as the SysMan Station, the SysMan Station authentication daemon, and the Logical Storage Manager (LSM) Storage Administrator, will not work correctly. Compaq OpenVMS The following table shows Java versions that are available athttp://www.compaq.com/java/alpha and indicates if the versionincludes the fix: Compaq OpenVMS - Java 1.1.8-5 (includes fix) Compaq OpenVMS - Java 1.2.2-3 Compaq OpenVMS - Java 1.3.0-2 (includes fix) Compaq OpenVMS - Java 1.3.1-2 (includes fix) It is critical that the information posted athttp://www.compaq.com/java/alpha be reviewed before updating Java.__________SUBSCRIBE:To subscribe to automatically receive future SecurityAdvisories from the Compaq's Software Security Response Team viaelectronic mail:http://www.support.compaq.com/patches/mailing-list.shtml_______REPORT:To report a potential security vulnerability with any Compaqsupported product, send emailmailto:security-ssrt () compaq comormailto:sec-alert () compaq comCompaq appreciates your cooperation and patience.
