==============1) Introduction
==============

>From the manual:
"The ASUS Remote Console (ARC) is an efficient and flexible application
that allows monitoring and control of the remote host."

The main component of this service is a telnet server listening on port
623 which is called DpcProxy and provides an IPMI interface.

=====2) Bug
=====

The DPC Proxy is affected by a buffer-overflow vulnerability located in
the function which gets the data received from the client, stores them
in a stack buffer of about 1024 bytes and checks the presence of an end
of line delimiter (carriage return).
