Subject       : netscape / Java development kit             Date   :  29-Mar-96
===============================================================================

By courtesy of NASIRC and CERT Coordination Center we received information on
vulnerabilities in netscape 2.01 and the Java development kit.

These vulnerabilities allow "booby-trapped" web-pages to compromise the
machine of anyone visiting this page with a Java-capable browser.

CERT-NL recommends obtaining vendor patches as soon as they become available.
Until then we urge you to apply the following workarounds:

     A. Java Development Kit users 

        Sun reports that source-level fixes will be supplied to source
        licensees in the next few days. The fixes will also be included in
        the next JDK version, v1.0.2, which will be released within the next
        several weeks. 

        The JDK itself is a development kit, and it can safely be used to
        develop applets and applications. If you choose to use the
        appletviewer as a rudimentary browser, do not use it to browse
        applets from untrusted sources until you have installed the v1.0.2
        browser. 

     B. Netscape users 

        If you use Netscape 2.0 install 2.01 and proceed as below.
        If you use Netscape 2.01, disable Java and JavaScript
  using the "Security Preferences" dialog box. 

        For the latest news about fixes for Netscape Navigator, consult
        the following for details:
