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.Query the planned and unplanned issuing status in the production order.我们选择把孩子生下,但是怎样和家里交代呢?校服能掩盖渐渐鼓起的肚子吗?该剧讲的是四个所谓的"不良少女"的秘密同居故事. 该剧以特殊的角度诠释了这些未婚妈妈,少年家长,离家出走等青少年经历的特殊问题. 懵懵懂懂怀孕的善希,已是未婚妈妈的星淑,性格叛逆的慧静,泼辣的晓媛,四个成长环境不同,人生遭遇各异但又都个性十足的女孩们住到了同一屋檐下,本剧讲述了正青春年少的她们的喜怒哀乐及成长故事.当初韩信有那明修栈道暗渡陈仓之计谋，有李斯和尉缭在洪都，他们对巴蜀和关中的地形可是极为熟悉的。这时，华夫人突然说道，如果承认的话，就把秋香许配给你。The weightlifting belt prevents spinal hyperextension by forming a hard posterior wall surrounding the lower torso and connecting the ribs and hip bones. This not only limits the backward movement of the spine, but also prevents the scoliosis and rotation of the spine. You can think of the belt as an external bone, which connects the ribs and hips by surrounding them, thus increasing stability. The strength weightlifting belt with the same width is designed according to this principle. Due to the large range of movements, the normal binding method (front binding) of the conventional weightlifting belt (narrow front and wide back) is also to achieve this goal.The second season of "Charming China City" has been upgraded completely, "Charming China City?
