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. 2. Affected Releases The following releases are affected: Windows Production Releases SDK and JRE 1.4.0 SDK and JRE 1.3.1_03 or earlier SDK and JRE 1.3.0_05 or earlier SDK and JRE 1.2.2_011 or earlier JDK and JRE 1.1.8_009 or earlier Solaris(TM) Operating Environment (OE) Reference Releases SDK and JRE 1.2.2_011 or earlier JDK and JRE 1.1.8_009 or earlier Solaris OE Production Releases SDK and JRE 1.4.0 SDK and JRE 1.3.1_03 or earlier SDK and JRE 1.3.0_05 or earlier SDK and JRE 1.2.2_11 or earlier JDK and JRE 1.1.8_15 or earlier Linux Production Releases SDK and JRE 1.4.0 SDK and JRE 1.3.1_03 or earlier SDK and JRE 1.3.0_05 or earlier SDK and JRE 1.2.2_011 or earlier Releases for JDK and JRE 1.1.x should no longer be used.
