cve-2013-5211 Vulnerability Description: Cve-2013-5211 was first announced January 10, 2014, because NTP itself does not verify the sender's source IP address. This is similar to the DrDoS (distributed reflection denial of service attack) used by the DNS parser. The attacker hack sent a forged message to the NTP server server A, changing the source IP address in the packet to the IP address of victim clien
