This update for ntp fixes the following issues :
ntp was updated to 4.2.8p15
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 victimβs ntpd instance could have modified the victimβs 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).
Removed an OpenSSL version warning (bsc#992038 and bsc#1125401).
