1. Background

   CERT has reported a bug in the zlib compression library
   (see www.cert.org/advisories/CA-2002-07.html).

   Sun's implementations of the Java(TM) Runtime Environment
   include zlib and are affected. This bug may allow malicious code
   to corrupt memory and possibly crash the Java Runtime Environment.

   The full and custom installations of Netscape 7 for Linux
   and the full and custom installations of Netscape 6 for Linux and
   Windows are affected since they include an affected version of the
   Java Runtime Environment. The default Java runtime environment of
   Netscape 7 for Windows is not affected. The default Java runtime
   environment of Netscape(TM) Communicator version 4.x is also
   not affected. For more information, see

           http://home.netscape.com/security

   The Microsoft VM is not affected.

   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 and JRE releases listed in section 3 of this bulletin.
