The attacker s goal is to create a situation in which the secure program determines that a given file name doesn t exist . the attacker then creates the symbolic link to another file , and then the secure program performs some operation , but now it actually opened an unintended file 攻擊者的目標(biāo)是,創(chuàng)造這樣一種情形,即讓安全程序判定某個(gè)給定的文件名并不存在,然后,攻擊者就可以創(chuàng)建指向另一個(gè)文件的符號(hào)鏈接,而后安全程序繼續(xù)執(zhí)行某些操作(但是現(xiàn)在,它打開的實(shí)際上是一個(gè)意料之外的文件) 。
