格式化字符串漏洞(Format String Vulnerability)是一种安全漏洞,通常出现在C/C++等编程语言中,当程序不正确地使用格式化函数(如printf, sprintf, fprintf等)并且格式化字符串是由用户输入控制时,就可能引发此类漏洞。攻击者可以利用这个漏洞读取程序的内存数据,甚至执行任意代码。 2. 阐述格式化字符串漏洞在

3. 格式化字符串漏洞(Format String Vulnerability):当程序在使用格式化字符串函数(如printf、sprintf等)时没有正确地处理格式化字符串参数时,攻击者可以通过构造恶意格式化字符串来读取或修改程序中的内存数据,从而实现对程序的控制。 4. 堆溢出攻击(Heap Overflow Attack):堆是程序运行时用于动态分配内存的区域。当程序...
