只因我来了东番，见到了船主，此地虽民不识字，却无半点沆瀣迂腐，虽名为海寇，行政事却比朝廷都要清明，船主虽年纪轻轻，却有吞四海之雄心，容百家之胸怀，仅此而已。龙且看到项羽脸上那一丝淡淡的忧虑，提议道：要不，先派人去彭城将虞姬夫人接到这里来。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.派出所民警丁捷和爱心医院呼吸科医生江箫的婚礼已多次推迟。在领导和同事们的多次催促下，他们终于放下工作，踏上了甜蜜的新婚旅程。谁知非典疫情突然爆发，出于强烈的责任感，他们毅然提前结束蜜月，立即返回了北京……
