通过update可以在fakeheap+0x8的位置伪造一个size,同时保证LIST中出现fakeheap+0x8的指针,绕过“你敢耍我”的检查。 通过update在fakeheap+0x10的位置写key1,key2设置为fakeheap+0x10这样key2会出现在LIST[11]的位置。 freeLIST[11],tcache下次就会返回fakeheap+0x10,这样就获得了一个LIST表的任意写,可以进行a...

I have a question for you: if you didn’t already know what the play was about, which of those 12 characters would you think was the most important to the story, based upon this account?
