Figure 1 is an example of a JOP attack. In this example, the attacker's aim is to execute a system call "int 0x80" to open a new command line window. To do this, an attacker needs to modify the contents of the eax register to "0x0000000b" and the ebx register to the string "/bin/sh" before "int 0x80" is called, and the ecx and edx registers must point to the value "0x00000000". Suppose the value "0x0000000" and the string "/bin/sh" can be found in memory when the program is running. An attacker needs to construct the value "0x0000000b" himself. However, for the value "0x0000000b", when an attacker saves data to the stack through a buffer overflow, the "0x00" byte will trigger the system to terminate the read operation. This example specifically describes how the attacker uses the existing code snippet in the program to modify the value of val pushed into the stack by the attacker step by step from "0xffffff0b" to the value required by the system call "0x0000000b", thus implementing JOP attack. The following are the detailed steps of the process.　　为摩尔神父辩护的是精明能干的女律师艾琳·布鲁勒(劳拉·琳妮饰)，她是一家律师事务所的合作人之一，也是一位典型的女强人。特别是在近期的一件高智商谋杀案中，艾琳凭着三寸不烂之舌将一个几乎被判定死罪的谋杀犯从铡刀下解救出来，并无罪释放。艾琳也因此跃升为律师界一颗耀眼的新星，备受关注。所以，当事务所的老板卡尔(柯姆·菲尔饰)将这件诉讼案交给艾琳时，她毫不犹豫地接了下来，因为这是她进一步扩大声誉、坐到事务所头把交椅的最佳良机。　　小镇盗窃案频频发生，一只梦想成为大侦探的猫咪为了找出真凶决定离家出走。旅途中的她遇到了一只自认风度翩翩的公鸡，一只梦想成为马戏团明星的驴，一只仇恨人类的守门狗。四只小动物历经磨合，即将找出真凶时，却被误认为是偷窃真凶。他们该如何证明清白，如何守护友谊和梦想……他们都清楚地意识到，匈奴南下会是一场灾难，越国和齐国都很难从中获益，匈奴会和他们讲信用吗？在他们忧心忡忡的时候，尹旭想到一个办法，那就是将计就计。我去骂他一顿，他就转过弯来了。本季分为三集，聚焦于三位荣获多个重量级奖项的音乐人。分别为H.E.R. aka Gabriella Wilson (E01), Kid Cudi aka Scott Mescudi (E02), 碧梨Billie Eilish (E03) ????逃命都不积极，那就是该死……季布骂了一句，看着前方奔逃的士兵，笑道：反倒是送死的积极，这世道……真是……楚军的杀戮更加刺激了诸侯联军的胆魄，有个人纷纷跪下，实在跑不动了，投降楚军或许能够换来一线生机。
