[docs] [issue24823] ctypes.create_string_buffer does not add NUL if len(init) == size

[Tom Pohl]

Tom Pohl added the comment:

I agree: not every buffer is null-terminated.

But the function name suggests that it creates a _string_ buffer which will most likely be used as an input to a C function. There, it can easily trigger a buffer overflow without a null termination which can be considered a severe security risk.
