ntp: ntpd crash when processing config commands with statistics type

It was found that ntpd would exit with a segmentation fault when a statistics type that was not enabled during compilation e.g. timingstats was referenced by the statistics or filegen configuration command...

ntp: stack exhaustion in recursive traversal of restriction list

A stack-based buffer overflow flaw was found in the way ntpd processed 'ntpdc reslist' commands that queried restriction lists with a large amount of entries. A remote attacker could use this flaw to crash ntpd...

ntp: incomplete checks in ntp_crypto.c

It was found that the fix for CVE-2014-9750 was incomplete: three issues were found in the value length checks in NTP's ntpcrypto.c, where a packet with particular autokey operations that contained malicious data was not always being completely validated. A remote attacker could use a specially...

ntpd crypto NAK Packet Denial of Service Vulnerability

ntpd is an operating system daemon that uses the Network Time Protocol to keep synchronized with the system time of a time server. A security vulnerability exists in ntpd that allows remote attackers to send crypto NAK packets with forged source addresses for denial-of-service attacks...

ntpd system time modification vulnerability (CNVD-2016-02740)

ntpd is an operating system daemon that uses the Network Time Protocol to keep synchronized with the system time of a time server. A security vulnerability in ntpd allows a remote attacker to modify a client's system time by forging packets and changing the basic client/server mode to an...

ntpd System Time Modification Vulnerability

ntpd is an operating system daemon that uses the Network Time Protocol to keep synchronized with the system time of a time server. A security vulnerability in ntpd exists when the program uses trustedkey and does not have the feature introduced in ntp-4.2.8p6 enabled, allowing a remote attacker t...

UBUNTU-CVE-2016-2516

NTP before 4.2.8p7 and 4.3.x before 4.3.92, when mode7 is enabled, allows remote attackers to cause a denial of service ntpd abort by using the same IP address multiple times in an unconfig directive...

UBUNTU-CVE-2016-1547

An off-path attacker can cause a preemptible client association to be demobilized in NTP 4.2.8p4 and earlier and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 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...

UBUNTU-CVE-2016-2518

The MATCHASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value...

UBUNTU-CVE-2016-1550

An exploitable vulnerability exists in the message authentication functionality of libntp in ntp 4.2.8p4 and NTPSec a5fb34b9cc89b92a8fef2f459004865c93bb7f92. An attacker can send a series of crafted messages to attempt to recover the message digest key...

UBUNTU-CVE-2016-1548

An attacker can spoof a packet from a legitimate ntpd server with an origin timestamp that matches the peer-dst timestamp recorded for that server. After making this switch, the client in NTP 4.2.8p4 and earlier and NTPSec aa48d001683e5b791a743ec9c575aaf7d867a2b0c will reject all future legitimat...
