CVE-2020-15025 (opens in a new tab)Amendment
The Ubuntu security team deemed this advisory irrelevant for Ubuntu:20.04.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ntpsec package and not the ntpsec package as distributed by Ubuntu.
ntpd in ntp 4.2.8 before 4.2.8p15 and 4.3.x before 4.3.101 allows remote attackers to cause a denial of service (memory consumption) by sending packets, because memory is not freed in situations where a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file.
