Weak Authentication

The Network Time Protocol NTP is used to synchronize a computer's time with a referenced time source. Multiple buffer overflow flaws were discovered in ntpd's cryptorecv, ctlputdata, and configure functions. A remote attacker could use either of these flaws to send a specially crafted request...

Denial Of Service (DoS)

ntp is vulnerable to denial of service DoS attacks. The vulnerability exists as a stack-based buffer overflow was found in the way the NTP autokey protocol was implemented. When an NTP client decrypted a secret received from an NTP server, it could cause that client to crash...

Check Point Gaia Operating System < R77.20 Multiple NTP Client Vulnerabilities (sk103825)

The remote host is running a version of Gaia Operating System that is prior to R77.20 and thus, is potentially affected by multiple NTP client vulnerabilities. Note that NTP client is disabled by default. Further note that if the vendor's suggested mitigations are in place, this can be considered...

CVE-2015-7704

The ntpd client in NTP 4.x before 4.2.8p4 and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service via a number of crafted "KOD" messages...

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...

Medium: ntp

Issue Overview: It was found that an ntpd client could be forced to change from basic client/server mode to the interleaved symmetric mode. A remote attacker could use a spoofed packet that, when processed by an ntpd client, would cause that client to reject all future legitimate server responses...
