Vulnerability from cnvd
Title
NTP ntpd代码注入漏洞
Description
ntpd（Network Time Protocol daemon）是一个操作系统守护进程，它使用网络时间协议（NTP）与时间服务器的系统时间保持同步。 基于Linux和OS X平台的NTP 4.2.8p1之前4.x版本的ntpd中的ntp_io.c文件中的‘read_network_packet’函数存在安全漏洞。由于程序未能正确确定源IP地址是否是IPv6回送地址。远程攻击者可通过从::1地址向ntpd机器的网络接口发送数据包，利用该漏洞伪造受限制数据包，读取或写入runtime状态。
