1. Background

   Under certain circumstances, the Java(TM) Runtime Environment may allow
   an untrusted Java class to call into a disallowed class. This is a
   potential security issue.

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

   To the best of Sun's knowledge, Netscape Navigator and Microsoft
   Internet Explorer are not exposed to this vulnerability.

   Sun recommends that you upgrade to the latest JDK/JRE releases
   listed in section 3 of this bulletin.


2. Affected Releases

   The following releases are affected:

     Windows Production and Solaris(TM) Reference Releases

     JDK/JRE 1.2.2_004 or earlier
     JDK/JRE 1.2.1_003 or earlier
     JDK/JRE 1.1.8_002 or earlier
     JDK/JRE 1.1.7B_005 or earlier
     JDK/JRE 1.1.6_007 or earlier

     Solaris Production Releases

     JDK/JRE 1.2.2_05 or earlier
     JDK/JRE 1.2.1
     JDK/JRE 1.1.8_10 or earlier
     JDK/JRE 1.1.7B
     JDK/JRE 1.1.6

     Linux Production Release

     JDK/JRE 1.2.2_005 or earlier

   Solaris Production releases JDK/JRE 1.2.1, 1.1.7B, and 1.1.6 should no
   longer be used. In addition, releases prior to JDK/JRE 1.1.6 for
   Windows or Solaris should no longer be used. Users of these releases
   should upgrade to a later release listed in Section 3.

   This vulnerability was fixed in Java 2 Standard Edition SDK v 1.3.

   The HotSpot(TM) 1.0 and 1.0.1 virtual machines are affected by this
   vulnerability. HotSpot 2.0 is not affected by this vulnerability.
   HotSpot 1.0 and 1.0.1 virtual machines should no longer be used.
   Users that cannot move to Java 2 Standard Edition SDK v 1.3 should revert
   to the Classic virtual machine in JDK/JRE 1.2.2_006 (Windows or Solaris
   reference).  Those users wishing to take advantage of the performance
   of HotSpot 2.0 should migrate to Java 2 Standard Edition SDK v 1.3.0.
