Description

This module exploits a vulnerability in the FlexNet
License Server Manager.

The vulnerability is due to the insecure usage of memcpy
in the lmgrd service when handling network packets, which
results in a stack buffer overflow.

In order to improve reliability, this module will make lots of
connections to lmgrd during each attempt to maximize its success.
