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. 3.
