作者:栈长@蚂蚁金服巴斯光年安全实验室 -------- 1. 背景 FFmpeg是一个著名的处理音视频的开源项目,非常多的播放器.转码器以及视频网站都用到了FFmpeg作为内核或者是处理流媒体的工具.2016年末paulcher发现FFmpeg三个堆溢出漏洞分别为CVE-2016-10190.CVE-2016-10191以及CVE-2016-10192.本文对CVE-2016-10190进行了详细的分析,是一个学习如何利用堆溢出达到任意代码执行的一个非常不错的案例. 2. 漏洞分析 FFmpe

堆栈溢出 堆栈溢出通常是所有的缓冲区溢出中最容易进行利用的.了解堆栈溢出之前,先了解以下几个概念: 缓冲区 简单说来是一块连续的计算机内存区域,可以保存相同数据类型的多个实例. 堆栈     堆 栈是一个在计算机科学中经常使用的抽象数据类型.堆栈中的物体具有一个特性:最后一个放入堆栈中的物体总是被最先拿出来,这个特性通常称为后进先出 (LIFO)队列.堆栈中定义了一些操作.两个最重要的是PUSH和POP.PUSH操作在堆栈的顶部加入一个元素.POP操作相反,在堆栈顶部移去一个 元素,并将堆栈的大

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

*** buffer overflow detected *** 是sprintf()超出buff大小

缓存溢出(Buffer overflow),是指在存在缓存溢出安全漏洞的计算机中,攻击者可以用超出常规长度的字符数来填满一个域,通常是内存区地址.在某些情况下,这些过量的字符能够作为“可执行”代码来运行.从而使得攻击者可以不受安全措施的约束来控制被攻击的计算机. 缓存溢出(或译为缓冲溢出)为黑客最为常用的攻击手段之一,蠕虫病毒对操作系统高危漏洞的溢出高速与大规模传播均是利用此技术. 缓存溢出攻击从理论上来讲可以用于攻击任何有缺陷不完美的程序,包括对杀毒软件.防火墙等安全产品的攻击以及对银行程序的
