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 NTP versions prior to 4.2.8p14 and 4.3.x before 4.3.100, remote attackers could exploit this vulnerability to cause a denial of service—resulting in the daemon exiting or the system time being changed. This was possible by predicting the transmit timestamps used in forged packets. The victim w...

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 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

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

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...

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...

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...

CVE-2026-66138

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...

Name of the Vulnerable Software and Affected Versions OpenStack Ironic Python Agent versions prior to 11.6.1 Description A project-scoped user with the manager role can achieve arbitrary code execution on a running Ironic-Python-Agent. This occurs because the value of the ntp server variable is...

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, allowing a malicious actor to execute arbitrary commands.

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...
