该漏洞被昵称为Dirty COW,因为底层问题是内核处理写时复制(COW)的方式。...Dirty COW已经存在了很长时间 - 至少自2007年以来,内核版本为2.6.22 - 所以绝大多数服务器都处于危险之中。...利用此错误意味着服务器上的普通,非特权用户可以获得对他们可以读取的任何文件的写入权限,因此可以增加他们对系统的权限。...但是,如果您运行的是较旧的服务器,则可以按照本教程确保您受到保护。 检查漏洞 Ubuntu版本/ Debian版本 要确定您的服务器是否受到影响,请检查您的内核版本。...---- 参考文献:《How To Protect Your Server Against the Dirty COW Linux Vulnerability》

简介 众所周知,在fork时,属于进程private的内存页将会进行COW机制。所谓COW,就是一个资源如果需要值拷贝,在读时不创建出副本,仅当写时再创建。...设置父子进程的所有内存页的标志为write protected, 而在mmap中被标识为shared的内存则会通过wp_page_reuse标记为wriable 因为谁先写不知道,所以两者都应该是wp,都能进行COW...这里产生了一个问题: 假如父子进程都使用COW,那么在子进程已经copy过的情况下,父进程再copy一次就会造成浪费。...COW 首先和常识相同,write这些页会触发page fault: handle_pte _fault linux使用handle_pte_fault函数处理: 如果vma是writable但是却触发了...总结 COW机制下,父子进程的页都会被标记为write protect 父子进程均有可能进行copy 最后一个写的进程不会进行copy,而是直接使用原本的物理页。
