4. Affected Components Description
==================================

JDENet is a network communication middleware that performs network 
communications workstation-to- server and server-to-server. It is used to call
remote functions, to autenticate users and transmit information between hosts 
in a JDEdwards environment.

5. Vulnerability Details
========================

If a message containing packets of a specific size is sent to the JDENET 
service, a Denial of service condition is triggered, because the kernel in
charge of dispatching those packets uses all the available CPU time.

Further technical details about this issue are not disclosed at this moment 
with the purpose of providing enough time to affected customers to patch
their systems and protect against the exploitation of the described 
vulnerability.

6. Solution
===========

Apply Oracle Critical Patch update January – 2012. More information available 
on http://www.oracle.com/technetwork/topics/security/cpujan2012-366304.html
