Abstract (en)

[origin: DE19846673A1] A method of preventing stack manipulation activity involves limiting any stack access, during a call to an unsafe function by hardware to the stack area of his unsafe function. Preferably, the limitation of stack access is carried out prior to the call to the unsafe function, with the reference stored on the stack frame of the called or polled function.
