Category:	Huawei EulerOS Local Security Checks
Title:	Huawei EulerOS: Security Advisory for ntp (EulerOS-SA-2020-1968)
Summary:	The remote host is missing an update for the Huawei EulerOS 'ntp' package(s) announced via the EulerOS-SA-2020-1968 advisory.
Description:	Summary: The remote host is missing an update for the Huawei EulerOS 'ntp' package(s) announced via the EulerOS-SA-2020-1968 advisory. Vulnerability Insight: A flaw was found in the Network Time Protocol (NTP), where a security issue exists that allows an off-path attacker to prevent the Network Time Protocol daemon (ntpd) from synchronizing with NTP servers not using authentication. A server mode packet with a spoofed source address sent to the client ntpd causes the next transmission to be rescheduled, even if the packet does not have a valid origin timestamp. If the packet is sent to the client frequently enough, it stops polling the server and is unable to synchronize with it.(CVE-2020-11868) 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 this flaw to modify the victim's clock by a limited amount or cause ntpd to exit.(CVE-2020-13817) Affected Software/OS: 'ntp' package(s) on Huawei EulerOS Virtualization for ARM 64 3.0.2.0. Solution: Please install the updated package(s). CVSS Score: 5.8 CVSS Vector: AV:N/AC:M/Au:N/C:N/I:P/A:P
