根据ctf-wiki总结栈溢出, 格式化字符串漏洞, 部分堆溢出利用, 制成如下思维导图 pwn.pdf

We’ve fine-tuned the 774M parameter GPT-2 language model using human feedback for various tasks, successfully matching the preferences of the external human labelers, though those preferences did not always match our own. Specifically, for summarization tasks the labelers preferred sentences copied wholesale from the input (we’d only asked them to ensure accuracy), so our models learned to copy. Summarization required 60k human labels; simpler tasks which continue text in various styles required only 5k. Our motivation is to move safety techniques closer to the general task of “machines talking to humans,” which we believe is key to extracting information about human values.

说是题目，其实就是飞秋0day 233 之前虽然听说过各种windows的pwn 软件停止更新已久，保护都没开，是比较古老的玩意儿了 于是很容易搜到各种POC 例如0x49D03F处的整形溢出 v54是输入进来的字符串，因此可以提供4294967295=0xffffffff=-1从而使memcpy发生缓冲区溢出的异常，然后通过覆盖SEH的方式进行利用 通过cyclic生成字符串填入，可以测出溢...
