Description

This ntp update to version 4.2.8p10 fixes serveral issues. This updated enables leap smearing. See /usr/share/doc/packages/ntp/README.leapsmear for details. Security issues fixed (bsc#1030050) :

- Copious amounts of Unused Code

- Off-by-one in Oncore GPS Receiver

- Makefile does not enforce Security Flags Bugfixes :

- Remove spurious log messages (bsc#1014172).

- clang scan-build findings

- Support for openssl-1.1.0 without compatibility modes

- Bugfix 3072 breaks multicastclient

- forking async worker: interrupted pipe I/O

- (...) time_pps_create: Exec format error

- Incorrect Logic for Peer Event Limiting

- Change the process name of forked DNS worker

- Trap Configuration Fail

- Nothing happens if minsane

- allow -4/-6 on restrict line with mask

- Move ntp-kod to /var/lib/ntp, because /var/db is not a standard directory and causes problems for transactional updates.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
