DATE CVE VULNERABILITY TITLE RISK
2017-08-07 CVE-2015-7691 Improper Input Validation vulnerability in NTP
The crypto_xmit function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (crash) via crafted packets containing particular autokey operations.

2017-07-24 CVE-2015-7703 Improper Input Validation vulnerability in NTP
The "pidfile" or "driftfile" directives in NTP ntpd 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77, when ntpd is configured to allow remote configuration, allows remote attackers with an IP address that is allowed to send configuration requests, and with knowledge of the remote configuration password to write to arbitrary files via the :config command.
4.3
2017-07-21 CVE-2015-5300 7PK - Time and State vulnerability in multiple Linux Systems
The panic_gate check in NTP before 4.2.8p5 is only re-enabled after the first change to the system clock that was greater than 128 milliseconds by default, which allows remote attackers to set NTP to an arbitrary time when started with the -g option, or to alter the time by up to 900 seconds otherwise by responding to an unspecified number of requests from trusted sources, and leveraging a resulting denial of service (abort and restart).
5.0
2017-07-21 CVE-2015-5219 Incorrect Type Conversion or Cast vulnerability in multiple products
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet.
7.5
2017-07-21 CVE-2015-5195 Improper Input Validation vulnerability in multiple products
ntp_openssl.m4 in ntpd in NTP before 4.2.7p112 allows remote attackers to cause a denial of service (segmentation fault) via a crafted statistics or filegen configuration command that is not enabled during compilation.

2017-07-21 CVE-2015-5194 Improper Input Validation vulnerability in multiple products
The log_config_command function in ntp_parser.y in ntpd in NTP before 4.2.7p42 allows remote attackers to cause a denial of service (ntpd crash) via crafted logconfig commands.
7.5
2017-03-27 CVE-2017-6458 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in multiple products
Multiple buffer overflows in the ctl_put* functions in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allow remote authenticated users to have unspecified impact via a long variable.

2017-01-30 CVE-2016-2519 Improper Restriction of Operations within the Bounds of a Memory Buffer vulnerability in NTP
ntpd in NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (ntpd abort) by a large request data value, which triggers the ctl_getitem function to return a NULL value.

4.9
2017-01-30 CVE-2016-2518 Out-of-bounds Read vulnerability in multiple products
The MATCH_ASSOC 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.

5.0
2017-01-30 CVE-2016-2517 Improper Input Validation vulnerability in NTP
NTP before 4.2.8p7 and 4.3.x before 4.3.92 allows remote attackers to cause a denial of service (prevent subsequent authentication) by leveraging knowledge of the controlkey or requestkey and sending a crafted packet to ntpd, which changes the value of trustedkey, controlkey, or requestkey.
