Title: tcpreplay堆缓冲区溢出漏洞（CNVD-2018-20537）

Description:

Tcpreplay是一套基于UNIX操作系统用于编辑和重放网络流量的开源实用程序。

Tcpreplay 4.3.0版本中的send_packets.c文件存在堆缓冲区溢出漏洞，该漏洞源于‘get_next_packet()’函数以不安全的方式使用‘memcpy()’函数将序列从源缓冲区pktdata拷贝到(*prev_packet)-&pktdata中。攻击者可利用该漏洞造成拒绝服务并可能泄露信息。

Severity: 中

Summary

Tcpreplay v4.3.0 beta1 contains a heap-based buffer over-read. The get_next_packet() function in the send_packets.c file uses the memcpy() function unsafely to copy sequences from the source buffer pktdata to the destination (*prev_packet)->pktdata. This will result in a Denial of Service (DoS) and potentially Information Exposure when the application attempts to process a file.
