论坛的人气上来了一点哦，大家来玩点“调试游戏”吧！让我们以“挑战”会友！ ^_^第一则挑战以基础为主，但是想完成好还是需要比较扎实的功底的。高手免看~=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=[背景]360的郑同学继江民、瑞星、微点之后又和大成天下的驱动飙上啦！ ^_^连续曝光的几个漏洞甚至把大成的吴总都炸出来了.. 呵呵http://hi.baidu.com/mj0011/blog/item/58b9367f2fcc870d29388a3d.htmlhttp://hi.baidu.com/mj0011/blog/item/8b8827d133bd393d9a50276c.htmlhttp://hi.baidu.com/mj0011/blog/item/0e66a2ded3c1a35dccbf1adc.htmlhttp://hi.baidu.com/mj0011/blog/item/4ee0b1ecd71a3a3827979132.htmlhttp://hi.baidu.com/mj0011/blog/item/6dd8c1a24e6078a8caefd06d.html我们这次的挑战以最近的漏洞入手——首页巡警v1.2及以下版本本地权限提升漏洞（任意内核地址写入）您可以在这里下载我整理好的文章（LaTeX）：http://advdbg.org/dfstore/img/ADVDBG%e5%86%85%e6%a0%b8%e8%b0%83%e8%af%95%e6%8c%91%e6%88%981.pdf细细观瞧这个漏洞，您会发现基本功是多么的重要啊。另外这个漏洞（和HkZwSetValueKey钩子不校验Ring3参数）也再次验证了那句经典的老话“一切输入都是有害的”。好了，挑战开始：1. 您能基于调试详细分析漏洞的原因及具体的危害吗？（蓝屏的原因不光有直接非法地址访问）2. 重现该漏洞驱动及攻击代码3. 写一个验证Ring3缓冲区安全性的函数——在以后自己的钩子里您也可以受益的 ^_^4. 单纯的任意内核地址写入Patch系统关键变量或0x90掉核心验证还不够好玩，你能写一段ShellCode让驱动跑个对话框出来吗？5. 另外太多太多可实践、讨论的完成的优秀的挑战者们将有机会获得 ADVDBG 年底将要出版的新书：《Showstopper : The Breakneck Race to Create Windows NT and the Next Generation at Microsoft》http://advdbg.org/blogs/advdbg_system/articles/370.aspxhttp://advdbg.org/blogs/advdbg_system/articles/506.aspx祝您好运！^_^
