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...

SUSE CVE-2020-13817

ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service daemon exit or system time change by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path...

UBUNTU-CVE-2021-46873

WireGuard, such as WireGuard 0.5.3 on Windows, does not fully account for the possibility that an adversary might be able to set a victim's system time to a future value, e.g., because unauthenticated NTP is used. This can lead to an outcome in which one static private key becomes permanently...

Code injection

Protectimus SLIM NFC 70 10.01 devices allow a Time Traveler attack in which attackers can predict TOTP passwords in certain situations. The time value used by the device can be set independently from the used seed value for generating time-based one-time passwords, without authentication. Thus, a...

Security Bulletin: Vulnerabilities in NTPv4 affect AIX (CVE-2020-11868, CVE-2020-13817, and CVE-2020-15025)

Summary There are vulnerabilities in NTPv4 that affect AIX. Vulnerability Details CVEID: CVE-2020-15025 DESCRIPTION: NTP is vulnerable to a denial of service, caused by a memory leak when a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file in ntpd. By sending...

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...

DEBIAN-CVE-2020-13817

ntpd in ntp before 4.2.8p14 and 4.3.x before 4.3.100 allows remote attackers to cause a denial of service daemon exit or system time change by predicting transmit timestamps for use in spoofed packets. The victim must be relying on unauthenticated IPv4 time sources. There must be an off-path...

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...
