IBM QRadar Network Security is affected by Network Time Protocol (NTP)
vulnerabilities of denial of service by flaw in ntpd, relying on
unauthenticated IPv4 time sources in ntpd.
Vulnerability Details
CVEID: CVE-2020-11868
DESCRIPTION: NTP is vulnerable to a denial of service, caused by a flaw in
ntpd. By sending a server mode packet with a spoofed source IP address, a
remote attacker could exploit this vulnerability to block unauthenticated
synchronization resulting in a denial of service condition.

CVEID: CVE-2020-13817
DESCRIPTION: NTP is vulnerable to a denial of service, caused by an issue when
relying on unauthenticated IPv4 time sources in ntpd. By predicting transmit
timestamps for use in spoofed packets, a remote attacker could exploit this
vulnerability to cause the daemon to crash or system time change.
CVSS Base score: 7.4
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/
