Description

The IBM 1.4.2 SR13-FP4 Java release includes the IBM Java 2 Runtime
Environment and the IBM Java 2 Software Development Kit.

This update fixes various vulnerabilities in the IBM Java 2 Runtime
Environment and the IBM Java 2 Software Development Kit. These
vulnerabilities are summarized on the IBM "Security alerts" page listed in
the References section. (CVE-2009-3555, CVE-2009-3867, CVE-2009-3869,
CVE-2009-3871, CVE-2009-3874, CVE-2009-3875)

For the CVE-2009-3555 issue, this update disables renegotiation in the
non-default IBM JSSE2 provider for the Java Secure Socket Extension (JSSE)
component. The default JSSE provider is not updated with this fix. Refer to
the IBMJSSE2 Provider Reference Guide, linked to in the References, for
instructions on how to configure the IBM Java 2 Runtime Environment to use
the JSSE2 provider by default.

When using the JSSE2 provider, unsafe renegotiation can be re-enabled using
the com.ibm.jsse2.renegotiate property. Refer to the following
Knowledgebase article for details:
