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.
