04 Aug 2023 — ntpd will crash if the server is not NTS-enabled (no certificate) and it receives an NTS-enabled client request (mode 3). It was discovered that ntpd in ntpsec, a secure, hardened, and improved implementation derived from the original NTP project, could crash if NTS is disabled and an NTS-enabled client request (mode 3) is received. • https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1038422 • CWE-372: Incomplete Internal State Distinction •

08 Jun 2021 — ntpkeygen can generate keys that ntpd fails to parse. NTPsec 1.2.0 allows ntpkeygen to generate keys with '#' characters. ntpd then either pads, shortens the key, or fails to load these keys entirely, depending on the key type and the placement of the '#'. This results in the administrator not being able to use the keys as expected or the keys are shorter than expected and easier to brute-force, possibly resulting in MITM attacks between ntp clients and ntp servers. For short AES128 keys, ntpd generates a w... • https://bugzilla.redhat.com/show_bug.cgi?id=1955859 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •

16 Jan 2019 — An issue was discovered in NTPsec before 1.1.3. Because of a bug in ctl_getitem, there is a stack-based buffer over-read in read_sysvars in ntp_control.c in ntpd. Se ha descubierto un problema en versiones anteriores a la 1.1.3 de NTPsec. Debido a un error en ctl_getitem, hay una sobrelectura de búfer en read_sysvars en ntp_control.c en ntpd. NTPsec version 1.1.2 suffers from an out-of-bounds read vulnerability in ctl_getitem. • https://packetstorm.news/files/id/151195 • CWE-125: Out-of-bounds Read •

02 May 2016 — ntpd in NTP 4.2.8p3 and NTPsec a5fb34b9cc89b92a8fef2f459004865c93bb7f92 relies on the underlying operating system to protect it from requests that impersonate reference clocks. Because reference clocks are treated like other peers and stored in the same structure, any packet with a source ip address of a reference clock (127.127.1.1 for example) that reaches the receive() function will match that reference clock's peer record and will be treated as a trusted peer. Any system that lacks the typical martian p... • http://www.oracle.com/technetwork/topics/security/bulletinapr2016-2952098.html • CWE-254: 7PK - Security Features •
