CVE-2015-7701 5 Debian, Netapp, Ntp and 2 more 13 Debian Linux, Clustered Data Ontap, Data Ontap and 10 more 2024-02-04 5.0 MEDIUM 7.5 HIGH
Memory leak in the CRYPTO_ASSOC 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 (memory consumption).
CVE-2015-8138 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
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-2017-6451 1 Ntp 1 Ntp 2024-02-04 4.6 MEDIUM 7.8 HIGH
The mx4200_send function in the legacy MX4200 refclock in NTP before 4.2.8p10 and 4.3.x before 4.3.94 does not properly handle the return value of the snprintf function, which allows local users to execute arbitrary code via unspecified vectors, which trigger an out-of-bounds memory write.
CVE-2017-6455 1 Ntp 1 Ntp 2024-02-04 4.4 MEDIUM 7.0 HIGH
NTP before 4.2.8p10 and 4.3.x before 4.3.94, when using PPSAPI, allows local users to gain privileges via a DLL in the PPSAPI_DLLS environment variable.
CVE-2016-2519 1 Ntp 1 Ntp 2024-02-04 4.9 MEDIUM 5.9 MEDIUM
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.
CVE-2015-7979 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 7.5 HIGH
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.
CVE-2017-6463 1 Ntp 1 Ntp 2024-02-04 4.0 MEDIUM 6.5 MEDIUM
NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote authenticated users to cause a denial of service (daemon crash) via an invalid setting in a :config directive, related to the unpeer option.
CVE-2015-7975 1 Ntp 1 Ntp 2024-02-04 2.1 LOW 6.2 MEDIUM
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-2016-2516 1 Ntp 1 Ntp 2024-02-04 7.1 HIGH 5.3 MEDIUM
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-2016-7433 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
NTP before 4.2.8p9 does not properly perform the initial sync calculations, which allows remote attackers to unspecified impact via unknown vectors, related to a "root distance that did not include the peer dispersion."
CVE-2016-2518 7 Debian, Freebsd, Netapp and 4 more 18 Debian Linux, Freebsd, Clustered Data Ontap and 15 more 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2016-7429 1 Ntp 1 Ntp 2024-02-04 4.3 MEDIUM 3.7 LOW
NTP before 4.2.8p9 changes the peer structure to the interface it receives the response from a source, which allows remote attackers to cause a denial of service (prevent communication with a source) by sending a response for a source to an interface the source does not use.
CVE-2016-1548 1 Ntp 1 Ntp 2024-02-04 6.4 MEDIUM 7.2 HIGH
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 legitimate server responses. It is possible to force the victim client to move time after the mode has been changed. ntpq gives no indication that the mode has been switched.
CVE-2016-7431 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
NTP before 4.2.8p9 allows remote attackers to bypass the origin timestamp protection mechanism via an origin timestamp of zero. NOTE: this vulnerability exists because of a CVE-2015-8138 regression.
CVE-2016-1550 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
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.
CVE-2016-1547 1 Ntp 1 Ntp 2024-02-04 5.0 MEDIUM 5.3 MEDIUM
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 authentication is enabled.
CVE-2016-9310 1 Ntp 1 Ntp 2024-02-04 6.4 MEDIUM 6.5 MEDIUM
The control mode (mode 6) functionality in ntpd in NTP before 4.2.8p9 allows remote attackers to set or unset traps via a crafted control mode packet.
CVE-2015-7977 8 Canonical, Debian, Fedoraproject and 5 more 12 Ubuntu Linux, Debian Linux, Fedora and 9 more 2024-02-04 4.3 MEDIUM 5.9 MEDIUM
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-2017-6452 1 Ntp 1 Ntp 2024-02-04 4.6 MEDIUM 7.8 HIGH
Stack-based buffer overflow in the Windows installer for NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via an application path on the command line.
CVE-2017-6458 4 Apple, Hpe, Ntp and 1 more 5 Mac Os X, Hpux-ntp, Ntp and 2 more 2024-02-04 6.5 MEDIUM 8.8 HIGH
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.
