Therefore, the opportunity and duration of the NPC and CPPCC reporters' questions are all very tight in the eyes of their peers. It is also because of this that conflicts among journalists in major conferences often occur.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.2. Add punctuation marks to the places where they are not punctuated in the text.陈先生，久仰大名，我现在走到哪，都能听到你的名字。花儿自幼喜欢唱歌，她的声音空灵而又美好，常常能够打动人心。终于，花儿的才华得到了听众们的肯定，她一夜爆红，成为了家喻户晓的明星，而她的眼疾亦因此有了治愈的希望。虽然打心眼里替妻子感到高兴，但张三斤感受到的更多的是不安与自卑。14. Do not issue a notice when the formulated plan is not confirmed. Since the plan confirmation notice is also issued to all departments, it should be implemented well. If it is not implemented for special reasons, it should be notified separately to facilitate all departments to arrange other work. Notices requiring assistance from various departments should include the main matters and the distribution of work, so as not to ask the relevant departments clearly and have no accurate answers.
