RHEL 4 / 5 : java-1.5.0-ibm (RHSA-2010:0130)

Synopsis :

The remote Red Hat host is missing one or more security updates.

Description :

Updated java-1.5.0-ibm packages that fix a security issue are now
available for Red Hat Enterprise Linux 4 Extras and 5 Supplementary.

This update has been rated as having moderate security impact by the
Red Hat Security Response Team.

The IBM 1.5.0 Java release includes the IBM Java 2 Runtime Environment
and the IBM Java 2 Software Development Kit.

A flaw was found in the way the TLS/SSL (Transport Layer
Security/Secure Sockets Layer) protocols handle session renegotiation.
A man-in-the-middle attacker could use this flaw to prefix arbitrary
plain text to a client's session (for example, an HTTPS connection to
a website). This could force the server to process an attacker's
request as if authenticated using the victim's credentials.
(CVE-2009-3555)

This update disables renegotiation in the Java Secure Socket Extension
(JSSE) component. Unsafe renegotiation can be re-enabled using the
com.ibm.jsse2.renegotiate property. Refer to the following
Knowledgebase article for details:
http://kbase.redhat.com/faq/docs/DOC-20491

All users of java-1.5.0-ibm are advised to upgrade to these updated
packages, containing the IBM 1.5.0 SR11-FP1 Java release. All running
instances of IBM Java must be restarted for this update to take
effect.
