An update that fixes 12 vulnerabilities is now available.

Description:

This update for ntp fixes the following issues:

when upgrading installations that have the file, but no key #1, which is
needed e.g. by “rcntp addserver”.

* CVE-2016-1547, bsc#977459: Validate crypto-NAKs, AKA: CRYPTO-NAK DoS.

* CVE-2016-2516, bsc#977452: Duplicate IPs on unconfig directives will

* CVE-2016-2517, bsc#977455: remote configuration trustedkey/
requestkey/controlkey values are not properly validated.
* CVE-2016-2518, bsc#977457: Crafted addpeer with hmode > 7 causes array
wraparound with MATCH_ASSOC.
* CVE-2016-2519, bsc#977458: ctl_getitem() return value not always
checked.
* integrate ntp-fork.patch
* Improve the fixes for: CVE-2015-7704, CVE-2015-7705, CVE-2015-7974
