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 authenticate users and transmit information between hosts in a JD Edwards environment.


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

If a certain type of message, containing a specially-crafted Unicode data packet, is sent to the JDENET Service, the JDENET Kernel executes a system
call, using a user-provided value as the time parameter. This causes the service to stop responding for a period of 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.
