CVE-2016-4954

The processpacket function in ntpproto.c in ntpd in NTP 4.x before 4.2.8p8 allows remote attackers to cause a denial of service peer-variable modification by sending spoofed packets from many source IP addresses in a certain scenario, as demonstrated by triggering an incorrect leap indication...

Network Time Protocol Crypto-NAK Preemptible Association Denial of Service Vulnerability

SUMMARY An off-path attacker can cause a preemptible client association to be demobilized by sending a crypto NAK packet to a victim client with a spoofed source address of an existing associated peer. This is true even if authentication is enabled. Furthermore, if the attacker keeps sending cryp...

Updated ntp packages fix security vulnerabilities

Updated ntp packages fix security vulnerabilities: The symmetric-key feature in the receive function in ntpproto.c in ntpd in NTP 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 th...

Design/Logic Flaw

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...

ntp: multiple issues

Keys explicitly generated by "ntp-keygen -M" should be regenerated. - CVE-2014-9293 weak key generation ntpd generated a weak key for its internal use, with full administrative privileges. Attackers could use this key to reconfigure ntpd or to exploit other vulnerabilities. - CVE-2014-9294 weak k...
