PROBLEM: A vulnerability exists in Java(TM) Secure Socket
          Extension(JSSE) where it may be possible under certain
          circumstances to gather information about the data
          transmitted over a Secure Sockets Layer (SSL) or a
          Transport Layer Security (TLS) channel with CBC
          encryption. The issue does not expose private or
          session keys.

          A second vulnerability exists where it may be possible
          under certain circumstances to extract private keys
          from an SSL server. This issue is described in

       http://crypto.stanford.edu/~dabo/abstracts/ssl-timing.html

IMPACT: This bug may introduce potential vulnerabilities into
          any program. These defects include the affected
          libraries. The resulting vulnerabilities may result
          in information leakage and improper code execution.

PLATFORM: Any HP-UX system (B.11.00, B.11.11, B.11.22, B.11.23)
          running the supported versions of 1.4.X is affected.
          In addition earlier JVM's (1.2.X, 1.3.X) using
          JSSE 1.0.3_01 is also affected.

SOLUTION: Update to version of Java with the security fixes.
          Note: Java 1.4.0 has been obsoleted by Sun and HP;
                no fix will be provided.

          For 1.4.1, manually update to version of Java with the
          security fixes: Java 1.4.1.04, or later.

          For JSSE 1.0.3_01, you will need to update 1.0.3_02.

MANUAL ACTIONS: Yes - update Java to: 1.4.1.04 or later.

          For Java versions (1.2.X, 1.3.X) using JSSE, update
          to 1.0.3_02 from the following URL:

          http://java.sun.com/products/jsse/index-103.html

AVAILABILITY: Updated releases are now available at:
              <www.hp.com/go/java>.
