首先是malloc的wrapper函数,会直接检查malloc返回的地址是否在fake heap当中,如果不是就会直接在fakeheap中做一次分配并返回地址。 还有一个memcpy wrapper,其中ALLOW_START/ALLOW_END是libc的起始和终止,如果调用这个函数来往libc写内容就会强制退出。 利用步骤 泄露libc,tcache泄露libc的方法不必多说,比较棘手的是解密脚本...

And a half-page that looked more like a program for a play than a synopsis at that. Remember, the goal here is brevity, not completeness, and the last thing you want to do is confuse our Millicent. Which is a very real possibility in a name-heavy synopsis, by the way: the more ...

By running the binary, we can see that it takes in a password as input, and that it must be at least 40 characters in length. Looking at themainfunction in prog.c, we can see that the program verifies the password, then initialises the key and shows the welcome message. ...
