CVE-2020-13817 – ntp: ntpd using highly predictable transmit timestamps could result in time change or DoS
https://notcve.org/view.php?id=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 attacker who can query time from the victim's ntpd instance. ntpd en ntp versiones anteriores a 4.2.8p14 y versiones 4.3.x versiones anteriores a 4.3.100, permite a atacantes remotos causar una denegación de servicio (salida del demonio o cambio de hora del sistema) mediante la predicción de las marcas de tiempo de transmisión para su uso en paquetes falsificados. La víctima debe confiar en fuentes de tiempo IPv4 no autenticadas. Debe haber un atacante fuera de la ruta que pueda consultar el tiempo desde la instancia ntpd de la víctima 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. • http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00005.html http://lists.opensuse.org/opensuse-security-announce/2020-07/msg00044.html http://support.ntp.org/bin/view/Main/NtpBug3596 https://bugs.ntp.org/show_bug.cgi?id=3596 https://security.gentoo.org/glsa/202007-12 https://security.netapp.com/advisory/ntap-20200625-0004 https://www.oracle.com/security-alerts/cpujan2022.html https://access.redhat.com/security/cve/CVE-2020-13817 https://bugzilla.redhat.com/show_bug& • CWE-330: Use of Insufficiently Random Values CWE-358: Improperly Implemented Security Check for Standard •
