- CVE-2020-11868: Fixed an issue which a server mode packet with spoofed source address
 frequently send to the client ntpd could have caused denial of service (bsc#1169740).
- CVE-2018-8956: Fixed an issue which could have allowed remote attackers to prevent
 a broadcast client from synchronizing its clock with a broadcast NTP server via spoofed
 mode 3 and mode 5 packets (bsc#1171355).
- CVE-2020-13817: Fixed an issue which an off-path attacker with the ability to query time
 from victim's ntpd instance could have modified the victim's clock by a limited amount (bsc#1172651).
- CVE-2020-15025: Fixed an issue which remote attacker could have caused denial of service by consuming
 the memory when a CMAC key was used andassociated with a CMAC algorithm in the ntp.keys (bsc#1173334).");
