High 7.4
Out-of-bounds Write in NTPsec
An out-of-bounds read and write in NTS client extension field parsing (extens_client_recv) in NTPsec before 1.2.5 allows a remote attacker who can send NTP server-mode replies to an NTS client to corrupt heap memory and crash ntpd, and, combined with the NTS-…

Out-of-bounds Read in NTPsec
An out-of-bounds read in the NTS-KE client response parser (nts_client_process_response_core) in NTPsec before 1.2.4 allows a malicious NTS-KE server to read the client's stack memory, including pointers that defeat ASLR, which the client then sends in cleart…

High 7.5
Out-of-bounds Read in ntpsec
Out-of-bounds read in NTS extension field parsing in NTPsec ntpd 1.1.4 through 1.2.5 allows a remote attacker to crash the daemon via an NTS Authenticator and Encrypted Extension Fields (AEEF) field with an oversized nonce length.

Medium 5.2
Out-of-bounds Read in ntpsec
Out-of-bounds read in the Motorola Oncore refclock driver in NTPsec ntpd before 1.2.6 allows an attacker who controls the GPS receiver's serial data to crash ntpd or disclose memory via a PPS Control (@@Gc) reply with an out-of-range mode byte.

Medium 6.4
Heap-based Buffer Overflow in ntpsec
Heap-based buffer overflow in the JJY refclock driver in NTPsec ntpd before 1.2.6 allows an attacker who controls the Telephone JJY time source to corrupt memory or crash ntpd via more than six time replies.

High 7.5
Reachable Assertion in ntpsec
Reachable exit in NTPsec ntpd 1.1.4 through 1.2.5 allows a remote attacker to terminate the daemon via an NTS request with excess NTS Cookie Placeholder extension fields.

Medium 4.7
Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') in ntpsec
Buffer overflow in NTPsec's Zyfer refclock allows local attacker to crash ntpd
-
High 7.5
Incomplete Internal State Distinction in ntpsec
ntpd will crash if the server is not NTS-enabled (no certificate) and it receives an NTS-enabled client request (mode 3).
