也好。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.SAGA主要讲述了AOI(葵车队)来了一个新的车手并驾御很厉害的跑车AL-zard(生物系统+稀有金属身体)，而因为实力上的差异，AOIFORMULA的主车手shinjonaoki，被淘汰，但是正当直辉为了重回CYBERFORMULA界顽强拼搏的同时，风见也为了和AL-ZARD较量而展开了激战。放下茶杯，沥海主宰者的声音不期而至。After the event is triggered, the method is executed. The first parameter of the method is bind when binding. Here, the calling function goes to the event pool to fetch what can be reused. If not, the new one is initialized.小声道：我大哥说，朝廷要扩建水军。　　TVB6月开拍时装女性爱情喜剧《爱美丽狂想曲》，已知主演有陈豪、李佳芯、萧正楠、曹永廉、杨诗敏等，监制罗永贤。
