  1. Background

    A vulnerability in the Java(TM) Runtime Environment Bytecode Verifier
    may be exploited by an untrusted applet to escalate privileges.

    The full and custom installations of Netscape 6.2.1 and earlier
    are affected since they include an affected version of the
    Java Runtime Environment. The default Java runtime environments of
    Netscape(TM) Communicator version 4.79 and earlier are affected.
    For more information, see

        http://home.netscape.com/security
    

    Microsoft VM up to and including build 3802 is affected.
    For more information, see

        http://www.microsoft.com/technet/security/bulletin/MS02-013.asp
    

    This issue may or may not affect other vendors' Java technology
    implementations which are derived from Sun's SDK and JDK(TM) source bases.
    Sun has notified and made the remedy available to its Java
    technology licensees.

    Sun recommends that users of affected releases upgrade to the latest
    SDK, JDK, and JRE releases listed in section 3 of this bulletin.
