The code drawbacks are as follows:早知如此，我就将那胡老大治好又如何。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.最终，鲁三还是没有受刑。该剧讲述了职场萌新记者程了与棋坛风云人物盛景初之间陪伴守护的治愈系甜恋故事，蕴含中华文化丰富内涵的创新题材搭配全新组合CP全运会上，电视台体育频道实习记者唐心奉命采访50米手枪慢射项目冠军，却发现对方并非大家看好的老将杜凌枫，而是四年前自己偷偷喜欢过的“射击馆辅导员”沈清源。沈清源在采访中的冷漠态度，让唐心大受打击，口吃起来，职场生涯也险被断送。唐心索性 以跟踪报道、制作节目等名义接近沈清源，试图从根源上解决问题。在省射击队，她邂逅了不甘落败的前手枪慢射冠军杜凌枫、争强好胜的女子气步枪选手石小辞、面嘻哈一面严肃的孪生兄弟陈宁陈海，制作出了备受欢迎的射击节目，破除了职场危机。亚锦赛召开在即，石小辞意外受伤，她选择将射击梦想交给杜凌风，唐心则在省队心理医生丁芳的帮助下，化解了沈清源埋藏至深的心结。昔日针锋相对的沈清源与杜凌枫最终冰释前嫌，他们怀抱着梦想与爱，并肩站在射击舞台上，向荣誉发起了更高的冲刺。
