CVE-2015-5219 Open this link in a new tabHow to fix?
Upgrade Debian:11 ntp to version 1:4.2.8p3+dfsg-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ntp package and not the ntp package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
The ULOGTOD function in ntp.d in SNTP before 4.2.7p366 does not properly perform type conversions from a precision value to a double, which allows remote attackers to cause a denial of service (infinite loop) via a crafted NTP packet.
