the description of Ja3BufferAppendBuffer() say "Append the second buffer to the first and then free it".
in all conditions after freeing second buffer, pointer to freed data replaced with NULL to avoid
further freeing. but if buffer1 contains no data - buffer2 is freed, but pointer left intact
and possibly there can be second call of free() on it.
right now it is seems impossible, as i cannot find a way, where Ja3BufferAppendBuffer() can
be called with (*buffer1)->data == NULL.
but it is better to append *buffer2 = NULL; after SCFree(*buffer2);
or just remove if ((*buffer1)->data == NULL) ... part
