Object Type Analysis, Overflow Context AnalysisandExploitability Evaluation. The componentDynamic Information Collection, of which the input is a PoC file, collects dynamic information during runtime by theruntime tracer, for example, instruction flow, memory read/write, and...
In this paper, we propose the Heap Overflow Exploitability Evaluator (Hoee), a new approach to automatically reveal the exploitability of heap buffer overflow vulnerabilities by evaluating proof-of-concepts (PoCs) generated by fuzzers. Hoee leverages several techniques to collect dynamic information ...
Heap Overflow 利用手法 kernel 2.6.23 之后默认用的应该都是 SLUB 如果只考虑单纯的堆溢出,利用内核对象进行简易版的堆喷是个可行的手法 以LK01-2 的洞为例,g_buf大小是 0x400,SLUB 分配时对应的对象就是 kmalloc-1024。而比较好利用的同样大小的内核对象是tty_struct,其用于保存一个 TTY 设备的信息,每次打...
Heap buffer overflows are a bit less straightforward to exploit than an equivalent stack overflow. The data that lies after a heap allocation is not a compiled-in stack frame, but some other heap object. The exact heap object that is is dependent on runtime factors rather than compile-time...
从上面的计算可以看出, 无论buffer开始地址多少, 当PAD为5,7,9的时候, 经过有限次列举总可以找到这样一个满足条件的位置. 我们取最小的数据5来构造我们的p3. [6]. 我们的exp 这样我们就可以写出exploit了: [netconf@linux1 challenge]$ cat exp4.c ...
FFmpeg RTMP Heap Buffer Overflow 漏洞分析及利用—【CVE-2016-10191】 作者:栈长@蚂蚁金服巴斯光年安全实验室 一、前言 FFmpeg是一个著名的处理音视频的开源项目,使用者众多。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。网上对CVE-2016-10190已经有了很多...
那么第一步就是如何控制RTMPPacket中的 data 指针了,我们先发一个 chunk 给客户端,CSID为0x4,程序为调用下面这个函数在堆上分配一个RTMPPacket[20] 的数组,然后在数组下面开辟一段buffer存储Message的 data。 if ((ret = ff_rtmp_check_alloc_array(prev_pkt_ptr, nb_prev_pkt, ...
Describe: A heap-buffer-overflow was discovered in zziplib v0.13.77. The issue is being triggered in function __zzip_parse_root_directory() at zzip/zip.c:539.Attackers may exploit this vulnerability to execute and cause a DOS attack. Rep...
