Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the ntp packages installed, the EulerOS Virtualization for ARM 64 installation on the remote host is affected by the following vulnerabilities :

- The Network Time Protocol (NTP) is used to synchronize a computer's time with another reference time source.
This package includes ntpd (a daemon which continuously adjusts system time) and utilities used to query and configure the ntpd daemon. Perl scripts ntp-wait and ntptrace are in the ntp-perl package, ntpdate is in the ntpdate package and sntp is in the sntp package. The documentation is in the ntp-doc package. Security Fix(es):NTP through 4.2.8p12 has a NULL Pointer Dereference.(CVE-2019-8936)Buffer overflow in the legacy Datum Programmable Time Server (DPTS) refclock driver in NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows local users to have unspecified impact via a crafted /dev/datum device.(CVE-2017-6462)NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote attackers to cause a denial of service (ntpd crash) via a malformed mode configuration directive.(CVE-2017-6464)NTP before 4.2.8p10 and 4.3.x before 4.3.94 allows remote authenticated users to cause a denial of service (daemon crash) via an invalid setting in a :config directive, related to the unpeer option.(CVE-2017-6463)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected ntp packages.
