I guess this buffer is the answer, unless the function returns
another pointer.

or:
nested_struct = [bufferSize, bufferType, buffer].pack("LLP")
struct = [version, numBuffers, inner_struct].pack("LLP")
nested_struct.unpack("LLP12")
If the function alters buffer of struct SecurityBuffer, says it
allocates new buffer and returns it, unpack can't deal with it.
You need DL instead.
