Microsoft has released security bulletin MS04-003 "Buffer Overrun in
MDAC Function Could Allow Code Execution (832483)".  The vulnerability
described in this bulletin is related to a buffer overflow in the MDAC
code which interprets responses to broadcast network messages.  A
vulnerable system must first initiate a broadcast message in order for an
attacker to send a malicious response, thus causing the buffer overflow
and possible execution of arbitrary code.  The execution of code would be
restricted to the same privileges of the program which initiated the
broadcast message, which in some cases may be the LocalSystem account.

Microsoft has rated the severity of this vulnerability as important.
