Fedora 38: 2023-611a143d5f Critical: Ntp-Refclock DoS Security Advisory

ntp-refclock is a wrapper for reference clock drivers included in the ntpd

daemon, which enables other NTP implementations to use the supported hardware

reference clocks for synchronization of the system clock.

It provides a minimal environment for the drivers to be able to run in a

separate process, measuring the offset of the system clock relative to the

reference clock and sending the measurements to another process controlling

the system clock.

Update to latest ntp-refclock and ntp, which fixes CVE-2023-26555.

* Thu Jun 1 2023 Miroslav Lichvar 0.6-1

- update ntp-refclock to 0.6 and ntp to 4.2.8p16
