Design/Logic Flaw

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...

Authentication flaw

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. NOTE:...

Null pointer dereference

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 ctlgetitem function to return a NULL value...

Design/Logic Flaw

NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to bypass the origin timestamp validation via a packet with an origin timestamp set to zero...

CVE-2015-7973

NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network...

CVE-2015-7976

The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename...

CVE-2015-7979

NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service client-server association tear down by sending broadcast packets with invalid authentication to a broadcast client...

DEBIAN-CVE-2015-7978

NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service stack exhaustion via an ntpdc relist command, which triggers recursive traversal of the restriction list...

CVE-2015-7973

NTP before 4.2.8p6 and 4.3.x before 4.3.90, when configured in broadcast mode, allows man-in-the-middle attackers to conduct replay attacks by sniffing the network...

CVE-2015-7977

ntpd in NTP before 4.2.8p6 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service NULL pointer dereference via a ntpdc reslist command...

CVE-2016-2518

CVE-2016-2518 affects NTP ntpd: MATCH_ASSOC() can trigger an out-of-bounds reference when handling addpeer with a large hmode. Affected versions are ntpd before 4.2.8p9 and 4.3.x before 4.3.92. Impact is a potential crash/denial of service via crafted packets. Mitigation: upgrade to fixed release...

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...

CVE-2016-2519

CVE-2016-2519 affects ntpd (NTP) before 4.2.8p7 and 4.3.x before 4.3.92. A remote attacker can trigger a denial of service by sending a large request data value that causes ctl_getitem to return NULL, leading to ntpd abort. The issue is a result of not always checking the return value of ctl_geti...

CVE-2015-7976

CVE-2015-7976 affects the ntpq saveconfig command in the NTP reference implementation (ntpd/ntpq) across multiple 4.x branches (e.g., 4.1.2, 4.2.x prior to 4.2.8p6, and 4.3.x). The underlying flaw is that saveconfig does not properly filter special characters in filenames, enabling an attacker to...

CVE-2015-8158

The getresponse function in ntpq in NTP versions before 4.2.8p9 and 4.3.x before 4.3.90 allows remote attackers to cause a denial of service infinite loop via crafted packets with incorrect values...

CVE-2015-7978

NTP before 4.2.8p6 and 4.3.0 before 4.3.90 allows a remote attackers to cause a denial of service stack exhaustion via an ntpdc relist command, which triggers recursive traversal of the restriction list...

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 ctlgetitem function to return a NULL value...

CVE-2015-7975

The nextvar function in NTP before 4.2.8p6 and 4.3.x before 4.3.90 does not properly validate the length of its input, which allows an attacker to cause a denial of service application crash...

CVE-2015-7976

The ntpq saveconfig command in NTP 4.1.2, 4.2.x before 4.2.8p6, 4.3, 4.3.25, 4.3.70, and 4.3.77 does not properly filter special characters, which allows attackers to cause unspecified impact via a crafted filename...
