How to determine if the installation is affected

Locate the file SW3eng.exe with Windows Explorer. For 3.0 and 3.0 SP1, the file is located in the "Program Files\CA\eTrust\Intrusion Detection\engine\" directory. For 2.0, the file is located in the "Program Files\eTrust\Intrusion Detection\engine\" directory.
Right click SW3eng.exe and choose Properties
Select the Version tab

The installation is vulnerable if the version of SW3eng.exe is less than the version indicated in the following table:
eTrust Intrusion Detection Release
