针对现有格式化串读写越界防御存在的问题,设计一种能够防御格式化串读写越界的虚拟机.通过分析格式化串读写越界防御虚拟机的行为,提出一种新的格式化串读写越界防御模型,给出了格式化串读写越界防御虚拟机的概要设计和详细设计.实验表明,该防御虚拟机能够加载和执行用户程序,能控制程序的执行流程,记录越界发生时进程内的内容,并提供保护、检测、响应和恢复功能.
針對現有格式化串讀寫越界防禦存在的問題,設計一種能夠防禦格式化串讀寫越界的虛擬機.通過分析格式化串讀寫越界防禦虛擬機的行為,提齣一種新的格式化串讀寫越界防禦模型,給齣瞭格式化串讀寫越界防禦虛擬機的概要設計和詳細設計.實驗錶明,該防禦虛擬機能夠加載和執行用戶程序,能控製程序的執行流程,記錄越界髮生時進程內的內容,併提供保護、檢測、響應和恢複功能.

Aim to the probelems of reading-writing-cross-border defense for format string, design a virtual machine that can de-fense reading-writing-cross-border action for the formatted string. By analyzing the reading-writing-cross-border action of the for-matted string, puts forward a new kind of reading-writing-cross-border defense model for format string, and gives the summary and detailed design the reading-writing-cross-border defense virtual machines. Experiments show that the defense virtual ma-chine can load and execute the user programs, and can control the execution process, record the content of the cross-border occurs within a process, and provide the function of the protection, the detection, the response and the recovery.
