CVE-2015-7871

Description

Unauthenticated off-path attackers can force ntpd processes to peer with malicious time sources of the attacker??s choosing allowing the attacker to make arbitrary changes to system time. This attack leverages a logic error in ntpd??s handling of certain crypto-NAK packets. When a vulnerable ntpd receives an NTP symmetric active crypto-NAK packet, it will peer with the sender bypassing the authentication typically required to establish a peer association.
