尤其是陈平的反间计奏效之后，范增因为背疽发作而亡，项羽对诸将的疑心更重。黎水笑眯眯地答道：当然累了。村庄的西面，横亘着连绵的山峦。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.? Disadvantages: Threads are not safe, and asynchrony is easy to occur in multithreading, such as frequent read and write operations on database objects.年过半百的Jay刚娶了美娇妻Gloria。最近Jay发现要应付年轻性感的老婆以及精力过剩的青春期继子Manny，让他有点力不从心。主妇Claire持家有道，可也有自己的难题。她的丈夫Phil是个好老公，只不过三个孩子让他有些心力交瘁。还有Mitchel和他热情四射的同性伴侣Cameron，他们刚做出了人生中的一个重大决定——领养一个名叫Lily的越南孤儿。
