我们可以先通过泄露出unsortbin的bins头来泄露libc的基址,然后将one_gadget的地址写入__malloc_hook,然后在进行分配的时候就能够getshell了。 我们可以先申请这样几块chunk:,然后我们就要想办法伪造一块free掉的chunk,使其fd指针指向unsortbin的bins头,然后进行输出泄露出地址。 我们可以对第0块chunk进行溢出,修改chun...

Coming back to theunlinkmacro, the following code is checking if the currentlyfreed chunkis alarge chunk(1) and that there are no larger chunks than this by checking thatP->fd_nextsizeis null(2). If this is the case it will do nothing as there is nothing to sort out regarding size ...
