这是CSAPP官网上的著名实验,通过注入汇编代码实现堆栈溢出攻击.实验材料可到我的github仓库 https://github.com/Cheukyin/CSAPP-LAB/ 选择buffer-overflow分支下载 linux默认开启ASLR,每次加载程序,变量地址都会不一样,所以若要关闭ASLR: sysctl -w kernel.randomize_va_space=0(赋值为2,即可打开ASLR) 不过本实验的程序似乎经过特殊处理,不需要关闭ASLR 正常编译的程序的stack是no…

 ORA-20000:ORU-10027:buffer overflow,limit of 2000 bytes.  这是因为在过程中用到了dbms_output.put_line()在服务器端输出信息,而serveroutput   的size默认定义为10000bytes. 修改一下size应该就可以了 set serveroutput on 30000 ORA-20000 string Cause:The stored procedure RAISE_APPLICATION_ERROR w…

-- These days I learned and studied buffer overflow. I like to write on the paper and it can keep synchronized for my brain.It is useful. -- To share these learning results, I use an App on Android to scan my drafts and put them on my draft. -- Keep…

Computer Systems A Programmer's Perspective Second Edition We have seen that C does not perform any bounds checking for array references, and that local variables are stored on the stack along with state information such as saved register values and…

下午的时候在 PL/SQl Developer 10.0.5.1710 上调试壹個存储过程,在调试的时候使用了比较多的 DBMS_OUTPUT.PUT_LINE 作为打印日志的方式,结果没过多久 PLSQL 客户端就开始提示如下错误:ORA-20000: ORU-10027: buffer overflow, limit of 10000 bytes,分析下来是因为函数DBMS_OUTPUT.PUT_LINE()是在循环体中打印结果的,因此,循环执行多少次,这個函数就会执行多少次, 导致缓冲区很…
