CVE-2014-9751
The readnetworkpacket function in ntpio.c in ntpd in NTP 4.x before 4.2.8p1 on Linux and OS X does not properly determine whether a source IP address is an IPv6 loopback address, which makes it easier for remote attackers to spoof restricted packets, and read or write to the runtime state, by...
The vulnerability of Cisco Nexus 1000V microprogramming software allows a remote attacker to gain unauthorized access to the device.
The function for receiving messages in the ntpproto.c file continues to operate even after an error message is displayed. This allows a remote attacker to gain unauthorized access to the device using specially crafted packets...
DEBIAN-CVE-2015-1798
The symmetric-key feature in the receive function in ntpproto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC...
UBUNTU-CVE-2015-1799
The symmetric-key feature in the receive function in ntpproto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service synchronization loss by spoofing the...
