Astra Linux – Vulnerability in NTP

In the mstolfp.c file within NTP 4.2.8p15, there is a buffer overflow vulnerability when a \0' character is added. An adversary may be able to attack a client ntpq process, but they cannot attack the ntpd process...

Astra Linux – Vulnerability in NTP

The praecisparse function in ntpd/refclockpalisade.c, within NTP 4.2.8p15, contains an out-of-bounds write vulnerability. Any attack method would be complex, for example, using a manipulated GPS receiver...

Astra Linux – Vulnerability in NTP

In the file libntp/mstolfp.c, within the NTP version 4.2.8p15, there is a buffer overflow vulnerability when copying the trailing number. An attacker may be able to exploit this vulnerability against a client’s NTPQ process, but they cannot exploit it against ntpd...

Astra Linux – Vulnerability in NTP

In the mstolfp.c file within NTP 4.2.8p15, there is a buffer overflow vulnerability when adding a decimal point. An adversary may be able to attack a client’s ntpq process, but they cannot attack the ntpd process...

Astra Linux – vulnerability in NTP

NTPD in NTP prior to versions 4.2.8p14 and 4.3.x prior to version 4.3.100 allows remote attackers to cause a denial of service by causing the daemon to exit or altering the system time by predicting transmission timestamps for use in spoofed packets. The victim must be relying on unauthenticated...

Astra Linux – Vulnerability in NTP

In NTP versions 4.2.8, 4.2.8p15, and 4.3.x, before 4.3.101, remote attackers could cause a denial of service memory consumption by sending packets. This occurs because memory is not released in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file...

Astra Linux – Vulnerability in NTP

In NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, ntpd allows an off-path attacker to block unauthenticated synchronization via a server mode packet with a spoofed source IP address. This occurs because transmissions are rescheduled even when a packet lacks a valid origin timestamp...

Astra Linux – Vulnerability in NTP

In ntp 4.2.8p10, 4.2.8p11, 4.2.8p12, and 4.2.8p13, remote attackers can prevent a broadcast client from synchronizing its clock with a broadcast NTP server through soofed modes 3 and 5. The attacker must either be part of the same broadcast network or control a slave device in that broadcast...

PT-2026-66833

Name of the Vulnerable Software and Affected Versions NTPsec affected versions not specified Description A buffer overflow occurs in the Zyfer refclock component of NTPsec. This issue allows a local attacker to cause a crash of the ntpd process by triggering a buffer copy without checking the siz...

CVE-2026-66138

A vulnerability was found in Ironic-Python-Agent's IPA time syncing code. The value of the ntpserver configuration option is inserted into a shell command without sanitization. This command is run as root very early in the IPA startup flow, allowing an attacker to run arbitrary commands as root...

EUVD-2026-48476

In OpenStack Ironic Python Agent through 11.6.0, a project-scoped user with the manager role can achieve arbitrary code execution on a running Ironic-Python-Agent via a maliciously constructed configuration, because the value of ntpserver is passed to a shell...

TOTOLINK A8000RU CGI Handler setNtpCfg Command Execution

The vulnerability of the setNtpCfg function in the /cgi-bin/cstecgi.cgi file of the CGI Handler component of the TOTOLINK A8000RU router’s software lies in the lack of measures to neutralize special elements. Exploiting this vulnerability could allow a remote attacker to execute arbitrary command...

CVE-2026-10655

The asynchronous SNTP client in Zephyr subsys/net/lib/sntp/sntp.c, sntpcloseasync closed the UDP socket file descriptor directly from the calling thread immediately after detaching it from the network socket service, without synchronizing with the socket-service poll thread. The socket service...
