Title: Tcpdump ICMPv6解析器缓冲区溢出漏洞

Description:

tcpdump是Tcpdump团队开发的一套运行在命令行下的嗅探工具。该工具允许用户拦截和显示发送或收到过网络连接到该计算机的TCP/IP和其他数据包。ICMPv6 parser是其中的一个互联网控制信息协议解析器。

tcpdump 4.9.2之前的版本中的ICMPv6解析器的print-icmp6.c文件的‘icmp6_print()’函数存在缓冲区溢出漏洞。远程攻击者可利用该漏洞造成拒绝服务（缓冲区越边界读取和应用程序崩溃）。

Severity: 高

Patch Name: Tcpdump ICMPv6解析器缓冲区溢出漏洞的补丁
