CVE-2020-15025

First published: Wed Jun 24 2020(Updated: )

NTP is vulnerable to a denial of service, caused by a memory leak when a CMAC key is used and associated with a CMAC algorithm in the ntp.keys file in ntpd. By sending specially-crafted packets, a remote authenticated attacker could exploit this vulnerability to consume all available memory resources.
