Time Protocol (NTP) Project NTP daemon (ntpd) could allow a remote
attacker to conduct spoofing attacks, caused by insufficient entropy
in PRNG. An attacker could exploit this vulnerability to spoof the
IPv6 address ::1 to bypass ACLs and launch further attacks on the
system. Network Time Protocol (NTP) Project NTP daemon (ntpd) is
vulnerable to a denial of service, caused by an error when using
symmetric key authentication. By sending specially-crafted packets to
both peering hosts, an attacker could exploit this vulnerability to
prevent synchronization."
