赵三叔，请你带他们几个往田畈去，看见干活的人就问。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.北京卫视《老师请回答》栏目是一档由中共北京市委教育工作委员会、北京市教育委员会指导，北京电视台卫视节目中心集结了最强团队研发制作，倾全力打造的全新样态的教育类节目。这是中国首档家庭教育公开课堂。节目每期走进一所首都优质示范校，集结众多教育名家、一线骨干教师，搭建学生、家长和学校之间沟通的桥梁，探讨切实解决全民关注的教育热点和难点。节目旨在帮助家长成为更好的家长，帮助孩子成为更好的孩子，帮助家长和孩子更好的沟通。在帮助家长解决问题的同时，在节目中展现首都教师队伍的师德师风，营造全社会尊师重教的浓厚氛围。都市白领李冰蓝，有着深爱自己的老公和幸福的小家。This is the second sub!故事发生在太行山深处、王莽岭脚下的沟里村。山修路，凿穿王莽岭的工程5年前进了100米。小庄计算这样干还得用80年，老支书听后惊呆了。小庄为竞选村长和老支书产生了误会。 　　小庄带领大家集资买电钻，新的工程开始了。老支书重新认识了小庄，却为排险石而牺牲。 　　除夕夜小庄一人守在工地，菊香为他送来了饺子，二人和好。结婚时，村民认为菊香名声不好，没人前来祝贺，菊香流下凄楚的眼泪。 　　小庄为动员村民上山修路，动手打了表弟大保。大保娘称赞小庄打得对，教育了儿子大保。一次爆破中大保重伤牺牲。 　　小庄的人格力量感动了沟里人，人们纷纷上山修路。路通了，全村人第—次看到了汽车进山，小庄来到了老支书和大保的坟前，默默地告慰在天之灵。
