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.As a result, there is no conflict between maternity leave and paid annual leave, and female employees can enjoy both maternity leave and paid annual leave.公元1898年，英国政府胁迫清廷展拓香港界址。易君恕拦轿求见李鸿章，恰在此时，一名蒙面男子突然持刀向李鸿章行刺，未遂。易君恕作为疑犯被当场抓获，李鸿章亲自审问，原来是故人之后，也未予治罪。危急时刻，易君恕被英国牧师林若翰搭救。迟孟桓正在追求林若翰之女倚阑，林若翰鄙视他，迟孟桓当面揭露了倚阑的身世,残酷的现实震撼了倚阑的心灵，和易君恕建立了相依为命的感情。迟孟桓把通缉告示密报港府警察司，要求逮捕易君恕。林若翰的老朋友骆克阻止了此举。《拓界》接管迫在眉睫，眉娘不顾自身安危，帮助邓伯雄购买了枪弹。易君恕撰写了《抗英保土歌》。林若翰、倚阑、易君恕陷入政治分歧和感情纠葛扭结的矛盾之中。易君恕在两广总督镇压中舌战方儒，感天撼地。邓伯雄率新安乡民与英军展开殊死捕斗，易君恕弹尽被捕,被判处绞刑。此刻，倚阑正经受产前折磨。一声啼哭，鲜血染红的产床上滚动着一个黑头发、黑眼睛的华夏男儿。走几步又停下，回头问道：井儿叔，要是我现在就另找个人嫁了，你说我算不算水性杨花？刘井儿忙喝道：瞎说啥。Discussion expert他正是这么想的，正等着呢。
