ntp was updated to fix two security related flaws as well as 'slew' mode handling for leap seconds.
The following vulnerabilities were fixe:
* ntpd could accept unauthenticated packets with symmetric key crypto. (CVE-2015-1798) * ntpd authentication did not protect symmetric associations against DoS attacks (CVE-2015-1799) * ntp-keygen may generate non-random symmetric keys on big-endian systems (bsc#928321, CVE-2015-3405).
