Learning design patterns does have several realms:In the past two years, the educational policy inclined to the direction of quality education has impacted on the examination-oriented counseling and training of mathematics and other disciplines, forcing some K12 discipline training institutions to begin to lay out the direction of quality education and explore the way of discipline quality education. For example, subject counseling agencies such as Learning and Thinking, New Oriental and Elite Education, with a keen sense of smell, have begun to work hard on the cultivation of children's thinking ability at an early stage.“梦中见到的男人。”虞子期笑道：若非霸王神机妙算，哪里能够成功？再者，说起来还真要感谢魏豹，魏军真的如约撤离的，还有这诸侯联军的营地之中的混乱，很多都是出自于魏军的手笔。-Liu Shiying (Financial Writer and Founder of President's Reading Club)On April 21, holding the attitude of testing, I made an appointment with my little partner to wear the product and went up the mountain, completing a total of 44.77 kilometers, lasting nearly 11 hours, with a cumulative altitude rise of 2823 meters.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.
