本文详细分析了 CVE-2016-10191 FFmpeg RTMP Heap Buffer Overflow 漏洞，提供了一个学习漏洞挖掘与利用的案例。漏洞发生在 FFmpeg 的 rtmppkt.c 文件中的 rtmp_packet_read_one_chunk 函数中，当 RTMP 协议中消息大小超出最大 chunk size 限制时，未正确校验 chunk size 的一致性，导致缓冲区溢出。...
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...
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, ...
Hi, there. A Heap-buffer-overflow problem was discovered in decompileJUMP function in util/decompile.c of libming v0.4.8. This problem can be reproduced in the latest code base, too. A crafted input can cause segment faults and I have co...
