-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Novell ZENworks Handheld Management.
Authentication is not required to exploit this vulnerability.

The specific flaw exists within module ZfHIPCND.exe. This process is
responsible for handling the data received on TCP port 2400. The module

buffer and execute arbitrary code with SYSTEM privileges.
