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
