What is "receive cmd permission"?

I encounter an unusual permission request when I attempt to update Norton Security Antivirus to ver 3.5.0.1023.  I have not updated it for a few months.  The app is requesting a few new permissions including one called "Receive cmd permission" under "Default".   When I select this permission, the description is "null".  I can not find any explanation or description on this site or elsewhere with Google, Bing, etc. I will not install an app, particularly a security app, with unusual, invalid or corrupt permission requests.  

 

Can anyone explain "Receive cmd permission" and why the description is null?    This situation shakes my confidence in this app.  If I can not resolve it, I will be moving to another vendor's security app.

 

Thanks,
