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...

ntp: ntpd using highly predictable transmit timestamps could result in time change or DoS

A high-performance ntpd instance that gets its time from unauthenticated IPv4 time sources may be vulnerable to an off-path attacker who can query time from the victim's ntpd instance. An attacker who can send a large number of packets with the spoofed IPv4 address of the upstream server can use...

CVE-2020-13817

CVE-2020-13817 affects ntp’s ntpd prior to 4.2.8p14 and 4.3.x prior to 4.3.100. An off‑path attacker can predict transmit timestamps in spoofed UDP packets to remote ntpd, causing a DoS via daemon exit or system time change when the victim relies on unauthenticated IPv4 time sources. Connected so...

CVE-2016-9042

A vulnerability was found in NTP, affecting the origin timestamp check function. An attacker able to spoof messages from all of the configured peers could send crafted packets to ntpd, causing later replies from those peers to be discarded, resulting in denial of service. Mitigation Implement...
