  • unsorted-bin-attack 这个文件文件原作者移动到glibc_2.27和glibc_2.23这两个文件夹中,和文中的内容不同,应该做过修改了,可以看下是否正确
  • 其他的是连接错误

最后提个建议

写文章的时候使用commit的序列号作为连接,这样就不会有引用连接错误问题

这里的超链接错误不能简单地从2.25修改到2.27,不同版本的glibc mitigation不同,利用方法也不一样,除了更新超链接还需要确保更新对应文档内容

这一点由于我们人手不足并且远离glibc多年,欢迎师傅@Ascotbe提交pr :)

不过使用commit id做为超链接确实是一种比较保险的方案,但具体可行性需要讨论一下,cc@iromise

因为没有任何检查,所以我们可以对同一个 chunk 多次 free,造成 cycliced list。
以 how2heap 的 [tcache_dup](https://github.com/shellphish/how2heap/blob/master/glibc_2.26/tcache_dup.c) 为例分析,源码如下:

只是提个建议,毕竟文档多起来如果引用其他项目不使用commit id,不是很好管理

PS:堆方面我还是初学者就不班门弄斧了

@bash-c@Ascotbe 使用 commit id 作为超链接确实是不错的解决方案。针对目前的情况,具体要改到哪一个 commit id 估计得手工找一下。不过最近比较忙,暂时没有时间来处理这个 o(╥﹏╥)o 。@Ascotbe 欢迎在学习的过程中给出 PR 鸭
