write up -- roarctf_2019_easy_pwn 简介 该题也是buu上的题目 64位小端的elf程序 该题的出题人将函数名全都抹除了,所以在我们进行反编译的时候,看到的函数名都是地址名来代替的,我们得自己分析各个函数的功能,然后可以选中函数名使用n键进行修改。
roarctf_2019_easy_pwn 1.利用off-by-one将chunk0修改后,释放掉chunk1,然后chunk1进入unsorted_bin中,申请一个合适大小的堆块,使剩余部分的刚好与chunk2重叠,最后通过show chunk2的内容泄露main_arena的地址。 注意:当申请一个从unsorted_bin中切割的堆块时,剩余的堆块在下次申请前仍然在unsorted_bin中...
